Subject: [PATCH 21/27] qtnfmac: extend "IE set" TLV to include frame type info
Date: Thu, 24 Aug 2017 19:30:18 -0700 [thread overview]
Message-ID: <20170825023024.10565-22-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>
Specifying frame type for "IE set" TLV will allow to use several
TLVs in a single message.
Modify users accordingly.
