Subject: [PATCH 04/16] iwlwifi: mvm: support v2 of the WoWLAN patterns command
Date: Tue, 23 Apr 2019 12:10:31 +0300 [thread overview]
Message-ID: <20190423091043.7156-5-luca@coelho.fi> (raw)
In-Reply-To: <20190423091043.7156-1-luca@coelho.fi>
From: Luca Coelho <luciano.coelho@intel.com>
Add new definitions for the WoWLAN patterns API version 2 and support
for version 2 of the WoWLAN patterns command without implementing the
new features. With this commit we only supporting the existing
bitmask pattern match. Use the new version only if the TLV is set.
