For user applications that use UD QPs, always resolve destination MAC
from the GRH.  This is to avoid failure due to any garbage value in
the attr->dmac.

ocrdma_query_ah() does not use correct macro, and checks the wrong bit
for the validity of address handle in vector table.  Fix this.

Because of IP-based GIDs, userspace AHs must have MAC and VLAN ID
resolved separately.  Presently, user AHs are broken for ocrdma.  This
patch resolves L2 addresses while creating user AH and obtains the
right DMAC and VLAN ID before creating AH.

Currently, driver obtains service level value from ah_attr->sl field.
However, this field is set to zero all the times from rdma-cm.  This
patch allows create_ah to obtain service level from dev->sl.

This patch implements routine to query the PFC priority from the
adapter port.

Following are the changes implemented:

 * A new FW command is implemented to query the operational/admin DCBX
   configuration from the FW and obtain active priority(service
   level).
 * Adds support for the async event reported by FW when the PFC
   priority changes. Service level is re-initialized during modify_qp
   or create_ah, based on this event.
 * Maintain SL value in ocrdma_dev structure and refer that as and
   when needed.

This patch is similar in spirit to the "IB/mlx4: Handle Ethernet L2
parameters for IP based GID addressing".  It handles the fact that IP
based RoCE gids don't store Ethernet L2 parameters, MAC and VLAN.

When building an address handle, instead of parsing the dgid to
get the MAC and VLAN, take them from the address handle attributes.
