When bringing down an interface netif_carrier_off() should be
one the first things we do, since this will prevent the stack
from queuing more packets to this interface.
This operation is very fast, and should make the device behave
much nicer when trying to bring down an interface under load.
Also, this would Do The Right Thing (TM) if this device has some
sort of fail-over teaming and redirect traffic to the other IF.
Move netif_carrier_off as early as possible.

While addressing the pin problem I noticed that all of the pin register
values where having to be pushed onto the stack each time the function was
called. To avoid that I am making them static const so that they should
only need to be allocated once and we can avoid all the instructions to get
them onto the stack..

When building the kernel using the gcc 4.8.3 compiler included in Fedora 20
I was repeatedly seeing the warning:
drivers/net/ethernet/intel/igb/igb_ptp.c: In function ‘igb_ptp_feature_enable_i210’:
drivers/net/ethernet/intel/igb/igb_ptp.c:395:21: warning: ‘pin’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
tssdp &= ~ts_sdp_en[pin];
^
drivers/net/ethernet/intel/igb/igb_ptp.c:471:6: note: ‘pin’ was declared here
int pin;
^
To resolve it I am assigning the pin a value of -1 when it is instantiated.

Starting I219, the NVM will not be mapped to its own BAR, but to an
address region in another bar. The mapping/unmapping is relevant
to older HW only.

The interface to the device flash was modified in i219 and later HW.
This patch better describes the change and the impact on the driver.

This patches implements the poll_controller support for all
bonding driver. If the slaves have poll_controller net_op defined,
this implementation calls them. This is mode agnostic implementation
and iterates through all slaves (based on mode) and calls respective
handler.

The driver implements ndo_switch_fib_ipv4_add/del ops to add/del/mod IPv4
routes to/from switchdev device. Once a route is added to the device, and the
route's nexthops are resolved to neighbor MAC address, the device will forward
matching pkts rather than the kernel. This offloads the L3 forwarding path
from the kernel to the device. Note that control and management planes are
still mananged by Linux; only the data plane is offloaded. Standard routing
control protocols such as OSPF and BGP run on Linux and manage the kernel's FIB
via standard rtm netlink msgs...nothing changes here.
A new hash table is added to rocker to track neighbors. The driver listens for
neighbor updates events using netevent notifier NETEVENT_NEIGH_UPDATE. Any ARP
table updates for ports on this device are recorded in this table. Routes
installed to the device with nexthops that reference neighbors in this table
are "qualified". In the case of a route with nexthops not resolved in the
table, the kernel is asked to resolve the nexthop.
The driver uses fib_info->fib_priority for the priority field in rocker's
unicast routing table.
The device can only forward to pkts matching route dst to resolved nexthops.
Currently, the device only supports single-path routes (i.e. routes with one
nexthop). Equal Cost Multipath (ECMP) route support will be added in followup
patches.
This patch is driver support for unicast IPv4 routing only. Followup patches
will add driver and infrastructure for IPv6 routing and multicast routing.

Using napi_complete_done() instead of napi_complete() allows
us to use /sys/class/net/ethX/gro_flush_timeout
GRO layer can aggregate more packets if the flush is delayed a bit,
without having to set too big coalescing parameters that impact
latencies.

its parameter type, so we should be using that instead of u32
or int.

Jeff Kirsher says:
====================
This series contains updates to i40e only.
Greg provides fixes for the NPAR transmit scheduler where the driver
initialization caused the BW configurations to not take effect, so use
a BW configuration read and write back to "kick" the transmit scheduler
into action. Fixes the ethtool offline test, where we were not actually
taking the device offline before doing the testing.
Matt modifies the get and set LED functions so they ignore activity LEDs
since we are required to blink the link LEDs only.
Neerav provides a workaround for whenever a DCBX configuration is changed,
where the firmware doe not set the operational status bit of the
application TLV status as returned from the "Get CEE DCBX Oper Cfg" admin
queue command. So remove the check for the operational and sync bits of
the application TLV status until a firmware fix is provided.
Shannon changes the driver to grab the NVM devstarter version and not
the image version, since it is the more useful version and is what
should be displayed. Moves the IRQ tracking setup and tear down into
the same routines that do the IRQ setup and tear down. This keeps
like activities together and allows us to track exactly the number
of vectors reserved from the OS, which may be fewer than are available
from the hardware.
Jesse provides a fix to use a more portable sign extension by replacing
0xffff.... with ~(u64)0 or ~(u32)0. Also fixes XPS mask when resetting,
where the driver would accidentally clear the XPS mask for all queues
back to 0. This caused higher CPU utilization and had some other
performance impacts for transmit tests. Cleans up some whitespace
formatting.
Catherine provides a fix where some firmware versions are incorrectly
reporting a breakout cable as PHY type 0x3 when it should be 0x16
(I40E_PHY_TYPE_10GBASE_SFPP_CU). Adds the 10G and 40G AOC PHY types
to the case statement in get_media_type and ethtool get_settings so
that the correct information gets reported back to the user.
Anjali provides IOREMAP changes for future device support, where we
do not want to map the whole CSR space since some of it is mapped by
other drivers with different mapping methods.
Mitch changes the i40e driver to not "spam" the system log with
messages about VF VSI when VFs are created and when they are reset to
reduce user annoyance.

The PF driver spams the system log with messages about VF VSI when VFs
are created, as well as each time they are reset. This is annoying, and
the information isn't even useful most of the time.
Remove this message to reduce user annoyance.

Move the IRQ tracking setup and teardown into the same routines that
do the IRQ setup and teardown. This keeps like activities together and
allows us to track exactly the number of vectors reserved from the OS,
which may be fewer than are available from the HW.

of it is mapped by other drivers with different mapping methods.
Note: As a side effect, the flash region (if exposed through the memory map)
gets unmapped too since it follows the future use region.

If we get this value back from FW and the version is < 4.40, reassign it
to I40E_PHY_TYPE_10GBASE_SFPP_CU.

During resets (possibly caused by a Tx hang) the driver would
accidentally clear the XPS mask for all queues back to 0.
This caused higher CPU utilization and had some other performance impacts
for transmit tests.

version which all the images for release will have the same version.
Of the two 0x18 is more useful and is what should be displayed.

In CEE mode the firmware does not set the operational status bit of
the application TLV status as returned from the "Get CEE DCBX Oper Cfg"
AQ command. This occurs whenever a DCBX configuration is changed.
This is a workaround to remove the check for the operational and sync bits
of the application TLV status till a firmware fix is provided.

To allow for better scalability on systems with large core counts, we
will try and allocate enough RDMA Concentrator IQs and MSI/X vectors as
we have cores. If we cannot get enough MSI/X vectors, fall back to the
minimum required: 1 per adapter rx channel.
Also clean up cxgb_enable_msix() to make it readable and correct a bug
where the vectors are not correctly assigned if the driver doesn't get
the full amount requested.

1. Use c_index and ring->c_index to determine how many TxCBs/TxBDs are
ready for cleanup
- c_index = the current value of TDMA_CONS_INDEX
- TDMA_CONS_INDEX is HW-incremented and auto-wraparound (0x0-0xFFFF)
- ring->c_index = __bcmgenet_tx_reclaim() cleaned up to this point on
the previous invocation
2. Add bcmgenet_tx_ring->clean_ptr
- index of the next TxCB to be cleaned
- incremented as TxCBs/TxBDs are processed
- value always in range [ring->cb_ptr, ring->end_ptr]
3. Fix incrementing of dev->stats.tx_packets
- should be incremented only when tx_cb_ptr->skb != NULL
These changes simplify __bcmgenet_tx_reclaim(). Furthermore, Tx ring size
can now be any value.
With the old code, Tx ring size had to be a power-of-2:
num_tx_bds = ring->size;
c_index &= (num_tx_bds - 1);
last_c_index &= (num_tx_bds - 1);

Now move and merge the useful contents of header file into driver code, note
the original header file is reserved for full registers set access test by other
code so it survives.

At the time of driver load the PF-pool resources are allocated to the PF.
When the user enables VFs, the resources are then re-distributed across
PFs and VFs based on the number of VFs enabled.

When SR-IOV is enabled in the adapter, the FW distributes resources
evenly across the PF and it's VFs. This is currently done only for some
resources.
This patch adds support for a new cmd that queries the FW for the list
of resources for which the distribution is allowed and distributes them
accordingly.

On BE2, BE3 and Skhawk-R chips one non-RSS (called "default") RXQ was
needed to receive non-IP traffic. Some FW versions now export a
capability called IFACE_FLAGS_DEFQ_RSS where this requirement doesn't hold.
On such FWs the driver now does not create the non-RSS default queue.
This prevents wasting one RXQ per VF.

The statistics registers have write-clear behaviour, which means we
will lose any increment between the read and write. Mitigate this by
only clearing when we read a non-zero value, so we will never falsely
report a total of zero. This also saves time as we only handle
error statistics here and they won't often be incremented.

There are many different sets of registers implemented by the
different versions of this controller, and we can only expect this to
get more complicated in future. Limit how much ethtool needs to know
by including an explicit bitmap of which registers are included in the
dump, allowing room for future growth in the number of possible
registers.
As I don't have datasheets for all of these, I've only included
registers that are:
- defined in all 5 register type arrays, or
- used by the driver, or
- documented in the datasheet I have
Add one new capability flag so we can tell whether the RTRATE
register is implemented.
Delete the TSU_ADRL0 and TSU_ADR{H,L}31 definitions, as they weren't
used and the address table is already assumed to be contiguous.

====================
Intel Wired LAN Driver Updates 2015-03-03
This series contains updates to fm10k, i40e and i40evf.
Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues. Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.
Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled. Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs. Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI. Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.
Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.
Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.
Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback. This
fix cleans up a bogus error message when removing the PF module with VFs
enabled. Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.
Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI. It is possible to enable as many as
num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33. Updates i40e/i40evf to add missing
packet types for VXLAN offload. Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB
per TC stats" since the stats should be in ethtool and not debugfs.

In case of MFP mode the driver was returning incorrect number of TCs
for partitions that are not enabled for iSCSI. Though the driver does
not configure these TCs in the Tx scheduler for the NIC partitions;
it does use this map to setup the queue mappings.
This patch fixes this and keeps all the NIC partitions to the default
PF TC i.e. TC0.

With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.
Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.
