Add geneve Rx offload support for x550em_a.

The implementation follows the vxlan code with the lower 16 bits of
the VXLANCTRL register holding the UDP port for VXLAN and the upper
for Geneve.

Disabled NFS filters in the RFCTL register which allows us to simplify
the check for VXLAN and Geneve packets in ixgbe_rx_checksum().

Removed vxlan from the name of the callback functions and replaced it
with udp_tunnel which is more in line with the new API.

The PF driver was only receiving the first 4 bytes of the MAC due
to an incorrect size parameter for ixgbevf_write_msg_read_ack()
in ixgbevf_set_rar_vf().

Correct the size by calculating it on a fly for all instances where
we call ixgbevf_write_msg_read_ack()

Correcting the mutex usage, in client_subtask(), mutex_unlock has
to be called just before client_del_instance() since this function opens
and later closes the same mutex again.
Similarly in client_is_registered removing the mutex since it closes
the mutex twice.

This is a patch suggested by RDMA team.

X722 hardware requires using the admin queue to configure RSS. This
function was previously re-written in commit e69ff813 ("i40e: rework
the functions to configure RSS with similar parameters").
However, the previous refactor did not work correctly for a few reasons

(a) it does not check whether seed is NULL before using it, resulting in
a NULL pointer dereference

This patch fixes the bug which causes RSS to continue to work
after being disabled.  After disabling RSS, traffic would continue
to be assigned to different queues instead of falling back to a
single queue. Without this patch, attempting to disable RSS would
not work as expected. This patch fixes the bug by clearing the
lookup table used by RSS such that all traffic is assigned to a
single queue.  This patch also addresses the issue of reinstating
 the lookup table should RSS then be re-enabled.

If a driver is unable to maintain all current user supplied settings
from ethtool (or other sources), it is not ok for a user request to
succeed and silently trample over previous configuration.

To that end, if you change the number of channels, it must not be
allowed to reduce the number of channels (queues) below the current
flow director filter rules targets. In this case, return -EINVAL when
a request to reduce the number of channels would do so. In addition
log a warning to the kernel buffer explaining why we failed, and report
the rules which prevent us from lowering the number of channels.

This patch fixes a problem where a static analysis tool generates
a warning for "INVARIANT_CONDITION: Expression 'enabled_tc' used
in the condition always yields the same result."

Without this patch, the driver will not pass the static analysis
tool checks without generating warnings.

This patch fixes the problem by eliminating the irrelevant check
and redundant assignment for the value of enabled_tc.

The function calls netif_set_real_num_(tx|rx)_queues, both of which
should be done only under rntl lock. Unfortunately the
i40evf_init_task did not hold the rtnl_lock as necessary. This patch
adds the locking needed.

When we are resetting the pf stats we should also reset the RX csum
error stat.

When we do a reset, all the VLAN filters get added again. Therefore we also
want to reset the VLAN count to 0 or we quickly run out of filters.

The client->open call in this path was not protected with the
client instance mutex, and hence the client->close can get initiated
before the open completes.
