scsi: qedf: Honor priority from DCBX FCoE App tag
We currently hard code the priority in the 8021q tag to 3 for FCoE
traffic. The vast majority of the time this is fine but if the priority
is something else besides 3, any VLAN ID comparison either in the
non-offload path or offload path will fail and cause dropped frames
where none are expected.
Change the behavior so that the driver default is 3 if we do not get any
DCBX convergence.
If DCBX does converge, then set the FIP/FCoE priority in the following
manner:
1. If the qedf_default_prio modparam is set use that
2. If the DCBX FCoE priority is not in range (0..7) use 3
3. Use the DCBX FCoE priority we get in the driver's DCBX handler
