Subject: [PATCH 6/6] ibmvfc: advertise client support for targetWWPN using v2 commands

The previous patch added support for the targetWWPN field in version 2
MADs and vfcFrame structures.

Set the IBMVFC_CAN_SEND_VF_WWPN bit in our capabailites flag during NPIV
Login to inform the VIOS that this client supports this feature.
