From: Parav Pandit <parav@xxxxxxxxxxxx>
When commit [1] was added, SGID was queries to derive the SMAC address.
Than later on during refactor [2], SMAC was no longer needed. However,
GID query remained.
This is discussed in [3].
[1] commit dd5f03beb4f7 ("IB/core: Ethernet L2 attributes in verbs/cm structures")
[2] commit 5c266b2304fb ("IB/cm: Remove the usage of smac and vid of qp_attr and cm_av")
