[ofa-general] [PATCH 2/2 v2] RDMA/nes: Change CQ allocation scheme for performance applications

[Chien Tung]

From: Vadim Makhervaks <vadim.makhervaks at intel.com>

RDMA/nes: New CQ allocation scheme for performance applications.

Fix CQ allocation for Mutli-Cast Receive Queue applications.  Before this
patch, CQ was not lined up with the right NIC.
