As Or points out in commit 423b3aecf290 ("net/mlx4: Change ENOTSUPP
to EOPNOTSUPP"), ENOTSUPP is NFS specific error. Replace it with
EOPNOTSUPP.

Since 83a77e9ec415, the phydev irq is explicitly set to PHY_POLL when
there is no pdata. It doesn't work on DT enabled platforms because the
phydev irq is already set by libphy before.

====================
40GbE Intel Wired LAN Driver Updates 2017-04-30
This series contains updates to i40e and i40evf only.
Jake provides majority of the changes in this series, starting with the
renaming of a flag to avoid confusion. Then renamed a variable to a
more meaningful name to clarify what is actually being done and to
reduce confusion. Amortizes the wait time when initializing or disabling
lots of VFs by using i40e_reset_all_vfs() and
i40e_vsi_stop_rings_no_wait(). Cleaned up a unnecessary delay since
pci_disable_sriov() already has its own delay, so need to add a additional
delay when removing VFs. Avoid using the same name flags for both
vsi->state and pf->state, to make code review easier and assist future
work to use the correct state field when checking bits. Use
DECLARE_BITMAP() to ensure that we always allocate enough space for flags.
Replace hw_disabled_flags with the new _AUTO_DISABLED flags, which are
more readable because we are not setting an *_ENABLED flag to
disable the feature.
Alex corrects a oversight where we were not reprogramming the ports
after a reset, which was causing us to lose all of the receive tunnel
offloads.
Arnd Bergmann moves the declaration of a local variable to avoid a
warning seen on architectures with larger pages about an unused variable.

This matches the ordering of how we free stuff during reset and remove.
It also makes logical sense because we set the interrupts based on the
number of queues. Currently this doesn't really matter in practice.
However a future patch moves the assignment of num_active_queues into
i40evf_alloc_queues, which is required by
i40evf_set_interrupt_capability.

The flag used by the common code and PF code is I40E_FLAG_FD_ATR_ENABLED,
not *FDIR*. It turns out none of the txrx code actually shared with the
VF driver actually checks the ATR flag. This is made even more obvious
by the typo in the VF header file.
Let's just remove the flag from the VF driver since it's not needed.

The hw_disabled_flags field was added as a way of signifying that
a feature was automatically or temporarily disabled. However, we
actually only use this for FDir features. Replace its use with new
_AUTO_DISABLED flags instead. This is more readable, because you aren't
setting an *_ENABLED flag to *disable* the feature.
Additionally, clean up a few areas where we used these bits. First, we
don't really need to set the auto-disable flag for ATR if we're fully
disabling the feature via ethtool.
Second, we should always clear the auto-disable bits in case they somehow
got set when the feature was disabled. However, avoid displaying
a message that we've re-enabled the feature.
Third, we shouldn't be re-enabling ATR in the SB ntuple add flow,
because it might have been disabled due to space constraints. Instead,
we should just wait for the fdir_check_and_reenable to be called by the
watchdog.
Overall, this change allows us to simplify some code by removing an
extra field we didn't need, and the result should make it more clear as
to what we're actually doing with these flags.

We already set pairs to the value of adapter->num_active_queues. This
value is limited by vsi_res->num_queue_pairs and num_online_cpus(). This
means that pairs by definition is already smaller than
num_online_cpus()*2, so we don't even need to bother with this check.
Lets just remove it and update the comment.

Instead of assuming our flags fit within an unsigned long, use
DECLARE_BITMAP which will ensure that we always allocate enough space.
Additionally, use __I40E_STATE_SIZE__ markers as the last element of the
enumeration so that the size of the BITMAP is compile-time assigned
rather than programmer-time assigned. This ensures that potential future
flag additions do not actually overrun the array. This is especially
important as 32bit systems would only have 32bit longs instead of 64bit
longs as we generally have assumed in the prior code.
This change also removes a dereference of the state fields throughout
the code, so it does have a bit of code churn. The conversions were
automated using sed replacements with an alternation
s/&(vsi->back|vsi|pf)->state/\1->state/
s/&adapter->vsi.state/adapter->vsi.state/
For debugfs, we modify the printing so that we can display chunks of the
state value on new lines. This ensures that we can print the entire set
of state values. Additionally, we now print them as 08lx to ensure that
they display nicely.

Avoid using the same named flags for both vsi->state and pf->state. This
makes code review easier, as it is more likely that future authors will
use the correct state field when checking bits. Previous commits already
found issues with at least one check, and possibly others may be
incorrect.
This reduces confusion as it is more clear what each flag represents,
and which flags are valid for which state field.

The delay was added because of a desire to ensure that the VF driver can
finish up removing. However, pci_disable_sriov already has its own
ssleep() call that will sleep for an entire second, so there is no
reason to add extra delay on top of this by using msleep here. In
practice, an msleep() won't have a huge impact on timing but there is no
real value in keeping it, so lets just simplify the code and remove it.

Just as we do in i40e_reset_all_vfs, save some time when freeing VFs by
amortizing the wait time for stopping queues. We can use
i40e_vsi_stop_rings_no_wait() to begin the process of stopping all the
VF rings at once. Then, once we've started the process on each VF we can
begin waiting for the VFs to stop. This helps reduce the total wait time
by a large factor.

This patch corrects a major oversight in that we were not reprogramming the
ports after a reset. As a result we completely lost all of the Rx tunnel
offloads on receive including Rx checksum, RSS on inner headers, and ATR.
The fix for this is pretty standard as all we needed to do is reset the
filter bits to pending for all active filters and schedule the sync event.

When allocating a large number of VFs, the driver previously used
i40e_reset_vf in a sequence. Just as when performing a normal reset,
this accumulates a large amount of delay for handling all of the VFs in
sequence. This delay is mainly due to a hardware requirement to wait
after initiating a reset on the VF.
We recently added a new function, i40e_reset_all_vfs() which can be used
to amortize the delay time, by first triggering all VF resets, then
waiting once, and finally cleaning up and allocating the VFs. This is
almost as good as truly running the resets in parallel.
In order to avoid sending a spurious reset message to a client
interface, we have a check to see whether we've assigned
pf->num_alloc_vfs yet. This was originally intended as a way to
distinguish the "initialization" case from the regular reset case.
Unfortunately, this means that we can't directly use i40e_reset_all_vfs
yet. Lets avoid this check of pf->num_alloc_vfs by replacing it with
a proper VSI state bit which we can use instead. This makes the
intention much clearer and allows us to re-use the i40e_reset_all_vfs
function directly.

The RSS key is being repopulated every time the interface is brought up
regardless of whether there is an existing value. If the user sets the RSS
key and the interface is brought up (e.g. reset), the user specified RSS
key will be overwritten.
This patch changes the rss_key to a pointer so we can check to see if the
key has been populated and preserve it accordingly.

Mailbox support for getting RETA and RSS is available for only 82599 and
x540; a previous patch reversed the logic and these adapters were
returning not supported.
Also, the NACK check in ixgbevf_get_rss_key_locked() was checking for the
command IXGBE_VF_GET_RETA instead of IXGBE_VF_GET_RSS_KEY.
This patch corrects both issues by correcting the logic and checking for
the right command.

Currently, there is no logic that allows a VF's MAC address to be removed
from the RAR table.
Allow the user to specify a zero MAC address in order to clear the VF's
MAC address from the RAR table. This functionality is also utilized by
libvirt when removing VFs.

Flush the macvlan filters on VF reset to avoid conflict with other VFs that
may end up using the same MAC address.
The main change here is the call to ixgbe_set_vf_macvlan() with index 0.
Moved ixgbe_set_vf_macvlan() in front of ixgbe_vf_reset_event() to avoid
adding a prototype.

Current XDP implementation hits the tail on every XDP_TX return
code. This patch changes driver behavior to only hit the tail after
packet processing is complete.
With this patch I can run XDP drop programs @ 14+Mpps and XDP_TX
programs are at ~13.5Mpps.

A couple design choices were made here. First I use a new ring
pointer structure xdp_ring[] in the adapter struct instead of
pushing the newly allocated XDP TX rings into the tx_ring[]
structure. This means we have to duplicate loops around rings
in places we want to initialize both TX rings and XDP rings.
But by making it explicit it is obvious when we are using XDP
rings and when we are using TX rings. Further we don't have
to do ring arithmatic which is error prone. As a proof point
for doing this my first patches used only a single ring structure
and introduced bugs in FCoE code and macvlan code paths.
Second I am aware this is not the most optimized version of
this code possible. I want to get baseline support in using
the most readable format possible and then once this series
is included I will optimize the TX path in another series
of patches.

The patch adds necessary changes to the driver to use qed resource
locking functionality. Currently the ptp initialization is spread
between driver probe/open implementations, associated APIs are
qede_ptp_register_phc()/qede_ptp_start(). Clubbed this functionality
into single API qed_ptp_enable() to simplify the usage of qed resource
locking implementation. The new API will be invoked in the probe path.
Similarly the ptp clean-up code is moved to qede_ptp_disable() which
gets invoked in the driver unload path.

This patch adds hardware channel APIs support between
VF and PF for tunnelling configuration for the VFs.
According to that configuration VFs can run VXLAN/GENEVE/GRE
tunnels over it with tunnel features offloaded.
Using these APIs VF can also request for UDP ports configuration
to the PF, although PF and it's child VFs share the same port.
