Subject: [PATCH 2/4] brcmfmac: don't allow arp/nd offload to be enabled if ap mode exists
Date: Tue, 1 Sep 2020 01:32:35 -0500 [thread overview]
Message-ID: <20200901063237.15549-3-wright.feng@cypress.com> (raw)
In-Reply-To: <20200901063237.15549-1-wright.feng@cypress.com>
From: Ting-Ying Li <tingying.li@cypress.com>
Add a condition to determine whether arp/nd offload enabling
request is allowed. If there is any interface acts as ap
mode and is operating, then reject the request of arp oflload
enabling from cfg80211.
