Subject: [PATCH 2/4] ath11k: pad mic len for protected action frames
Date: Tue, 28 May 2019 14:52:54 -0700	[thread overview]
Message-ID: <1559080376-26817-3-git-send-email-pradeepc@codeaurora.org> (raw)
In-Reply-To: <1559080376-26817-1-git-send-email-pradeepc@codeaurora.org>

padding mic space is necessary for firmware to generate mic len
correctly and to not run into any memory issues.
