Subject: [PATCH 06/27] qtnfmac: pass full channel definition to device on start_ap command
Date: Thu, 24 Aug 2017 19:30:03 -0700	[thread overview]
Message-ID: <20170825023024.10565-7-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>

Introduce chandef TLV and pass it to wireless card on start_ap
command processing.
No need to cache chandef in driver private structure as it is
not used anywhere.
