The arm writeback (arm_wb) code is used for kicking the Tx ring to
make sure any pending work is completed even if interrupts are
disabled. It was running when it didn't need to, and not clearing
the ring->arm_wb state after it was set. This caused Tx hangs
to still occur occasionally when there really was no hang.
Fix this by resetting the variable right after it was used.

The struct i40e_aqc_get_cee_dcb_cfg_v1_resp was originally defined with
word boundary layout issues, which most compilers deal with by silently
adding padding, making the actual struct larger than designed.
This patch adds an extra byte in fields reserved3 and reserved4 to directly
acknowledge that padding.
Because the struct doesn't actually change in size or layout, this doesn't
constitute a change in the API.

If a port VLAN is set for a given virtual function (VF) before the VF
driver is loaded then a configuration error results in which the port

patch ensures that the port VLAN filter is considered at the right time
during configuration of the VF's MAC/VLAN filters.

This patch fixes the issue of forcing WB too often causing us to not
benefit from NAPI.
Without this patch we were forcing WB/arming interrupt too often taking
away the benefits of NAPI and causing a performance impact.
With this patch we disable force WB in the clean routine for X710
and XL710 adapters. X722 adapters do not enable interrupt to force
a WB and benefit from WB_ON_ITR and hence force WB is left enabled
for those adapters.
For XL710 and X710 adapters if we have less than 4 packets pending
a software Interrupt triggered from service task will force a WB.
This patch also changes the conditions for setting RS bit as described
in code comments. This optimizes when the HW does a tail bump and when
it does a WB. It also optimizes when we do a wmb.

Fix the FLOGI discovery logic to comply with T11 standards
We weren't properly setting fabric parameters, such as R_A_TOV and E_D_TOV,
when we registered the vfi object in default configs and pt2pt configs.
Revise to now pass service params with the values to the firmware and
ensure they are reset on link bounce. Required reworking the call sequence
in the discovery threads.

kmalloc() can return NULL and without checking we were dereferencing it.
Moreover if kmalloc succeeds but the function fails in other parts then
we were returning the error code but we missed freeing lcb_context.
While at it fixed one related checkpatch warning.
