Subject: [PATCH v3 6/6] ibmvfc: advertise client support for targetWWPN using v2 commands
Date:   Tue, 17 Nov 2020 19:11:04 -0600
Message-Id: <20201118011104.296999-7-tyreld@linux.ibm.com>

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 the feature.
