Merge branch 'bnxt_re_variable_wqes' into rdma.git for-next
Selvin Xavier says:
=============
Enable the Variable size Work Queue entry support for Gen P7
adapters. This would help in the better utilization of the queue memory
and pci bandwidth due to the smaller send queue Work entries.
=============
Based on v6.11-rc5 for dependencies.
