Subject: [PATCH 08/27] qtnfmac: get rid of QTNF_STATE_AP_START usage
Date: Thu, 24 Aug 2017 19:30:05 -0700	[thread overview]
Message-ID: <20170825023024.10565-9-igor.mitsyanko.os@quantenna.com> (raw)
In-Reply-To: <20170825023024.10565-1-igor.mitsyanko.os@quantenna.com>

From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>

QTNF_STATE_AP_START usage is redundant and imposes additional state
synchronization maintenance. We may as well leave state checking up
to network card and upper layers (cfg80211, nl80211 and userspace).
