Subject: cxgb4: number of VFs supported is not always 16
Patch-mainline: v5.0-rc1
Git-commit: 1b974aa43ae22b4626721d11dd755a8541bb32de
References: bsc#1127354

Total number of VFs supported by PF is used to determine the last
byte of VF's mac address. Number of VFs supported is not always
16, use the variable nvfs to get the number of VFs supported
rather than hard coding it to 16.
