This patch removes the rval variable returns from function and replaces
them with direct returns in ixgbe_dcbnl_getnumtcs. It also changes how
ixgbe_gstrings_test is copied into data with memcpy in ixgbe_get_strings
because "*ixgbe_gstrings_test too small (32 vs 160)".

This patch adds a default case which goes to the next loop iteration
in the case where p is not set, preventing p from being dereferenced.

There are enough register offsets to warrant being in their own header
file, and doing so logically separates them from other header file content.
They have been converted from an enumerated data type to #defines as is
done in all the other Intel wired ethernet drivers.

Move #defines, function prototypes and data types which are applicable to
all/most devices supported by the driver but are specific to the
manageability component of each device to the new manage.h header file.
These #defines, function prototypes and data types can be used by other
files in the driver and moving them to the manageability-specific file
makes it clearer to which component they are applicable.

net/ipv6/route.c
The ipv6 route.c conflict is simple, just ignore the 'net' side change
as we fixed the same problem in 'net-next' by eliminating cached
neighbours from ipv6 routes.
The e1000e conflict is an addition of a new statistic in the ethtool
code, trivial.
The vmxnet3 conflict is about one change in 'net' removing a guarding
conditional, whilst in 'net-next' we had a netdev_info() conversion.
The iwlwifi conflict is dealing with a WARN_ON() conversion in
'net-next' vs. a revert happening in 'net'.

1) rhine_tx() should use dev_kfree_skb() not dev_kfree_skb_irq()
2) rhine_slow_event_task's NAPI triggering logic is racey, it
should just hit the interrupt mask register. This is the
same as commit 7dbb491878a2c51d372a8890fa45a8ff80358af1
("r8169: avoid NAPI scheduling delay.") made to fix the same

In rare instances, memory errors have been detected in the internal packet
buffer memory on I217/I218 when stressed under certain environmental
conditions. Enable Error Correcting Code (ECC) in hardware to catch both
correctable and uncorrectable errors. Correctable errors will be handled
by the hardware. Uncorrectable errors in the packet buffer will cause the
packet to be received with an error indication in the buffer descriptor
causing the packet to be discarded. If the uncorrectable error is in the
descriptor itself, the hardware will stop and interrupt the driver
indicating the error. The driver will then reset the hardware in order to
clear the error and restart.
Both types of errors will be accounted for in statistics counters.

Commit ee873fda3bec7c668407b837fc5519eb961fcd37
"gianfar: Pack struct gfar_priv_grp into three cachelines"
causes the following null dereference at driver init on sbc8548:
libphy: Freescale PowerQUICC MII Bus: probed
Unable to handle kernel paging request for data at address 0x00000000
Faulting instruction address: 0xc01d6a38
Oops: Kernel access of bad area, sig: 11 [#1]
[...]
NIP [c01d6a38] gfar_parse_group+0x228/0x280
LR [c01d6a34] gfar_parse_group+0x224/0x280
Call Trace:
[ef82dd60] [c01d6a34] gfar_parse_group+0x224/0x280 (unreliable)
[ef82dd90] [c01d73a4] gfar_probe+0x284/0xfe0
The reason is that the commit also changed the allocation of the
Rx and error handling irq structs to be skipped for !MQ_MG_MODE.
In the !MQ_MG_MODE case, only the Tx irq struct is allocated.
Digging further, we see that MQ_MG_MODE is set only if we find
the OF compatible string "fsl,etsec2".
A quick grep in the dts directory shows lots of boards that support
Rx/Tx/Err, but without this specific compat string. And hence they
go after the unallocated Rx/Error structs and cause the above oops.
Hence such a change can not be deployed until all the dts files
are updated and sufficiently deployed. Further, the optimization
is of limited value, since the kmalloc'd struct in question has only
a single unsigned int, and an (IFNAMSIZ + 6) sized string.
Note that no changes to the freeing code are needed here, as it
already did an unconditional free of Rx/Tx/Error gfar_irqinfo.

Currently, when the PF driver is unloaded and re-loaded while VFs are attached
to VMs, it loses control of its VFs.
The PF driver now uses the newly defined/created GET_IFACE_LIST cmd
(available in FW ver >= 4.6) to query the if_id of the VFs
(enabled in its previous life). The PF driver then uses the if_id for
further VF configuration.
The GET_IFACE_MAC_LIST cmd has also implemented in BE3 FW for PF to
query pmac-ids used by its VFs.

We actually store the MAC address as well as the board_name here. The
longest board_name is 75 characters so there is more than enough room
to hold the 17 character MAC and the ": " divider. But making this
buffer larger silences a static checker warning.

When the interface does not have carrier but when it's put into
loopback mode (for tests), it does not make sense to not have
the carrier. So force it!

For standard IEEE MII-compatible transceivers, the kernel has generic
register and bit definitions. Use those instead of redundant local
defines.
Do not replace references of MII_CR_SPEED_10 with BMCR_SPEED10 (0x0000)
when it is not necessary (i.e. when it is bitwise OR'ed with another
value).
Some whitespace issues in the surrounding context of the above changes are
also cleaned up.

Under heavy CPU load, changing, ring size/mtu/etc. could result in transmit
timeout, since stop-start port might take more than 10 seconds.
Calling netif_detach_device to prevent tx queue transmit timeout.
netif_detach_device() is not called under ndo_stop, because netif_carrier_off
will prevent the timeout, and device should not be marked as not present, or
else user won't be able to start it later on.

The Firmware dynamically changes flow steering hash configuration from covering
L2 only to "full" L2/L3/L4 mode needed. The dynamic change allows the driver
to set hard coded hash configuration which is changed by the firmware from L2
to L2/L3/L4 when attaching the first L3/L4 flow steering rule and back to L2
when there are no more such rules.
