Subject: [PATCH v1] af/rvu_cgx: Fix missing check bugs in rvu_cgx.c
Date: Tue, 29 Dec 2020 23:24:26 -0800	[thread overview]
Message-ID: <1609313066-5353-1-git-send-email-wangyingjie55@126.com> (raw)

From: Yingjie Wang <wangyingjie55@126.com>

In rvu_mbox_handler_cgx_mac_addr_get() and rvu_mbox_handler_cgx_mac_addr_set(),
the msg is expected only from PFs that are mapped to CGX LMACs.
It should be checked before mapping, so we add the is_cgx_config_permitted() in the functions.
