Subject: [PATCH] mwifiex: check for mfg_mode in add_virtual_intf
Git-commit: 26177d7f3969da1827bc2b5923edcfc2ff4c3a61
Patch-mainline: v4.15-rc1
References: FATE#326294

If driver is loaded with 'mfg_mode' enabled, then the sending
commands are not allowed. So, skip sending commands, to firmware
in mwifiex_add_virtual_intf if 'mfg_mode' is enabled.
