Subject: [PATCH 0/8] enic:enable 32, 64 byte cqes and get max rx/tx ring
 size from hw

This series enables using the max rx and tx ring sizes read from hw.
For newer hw that can be up to 16k entries. This requires bigger
completion entries for rx queues. This series enables the use of the
32 and 64 byte completion queues entries for enic rx queues on
supported hw versions. This is in addition to the exiting (default)
16 byte rx cqes.
