Subject: [PATCH 15/16] wcn36xx: don't pad beacons for mesh
Date: Mon, 28 Mar 2016 23:06:32 -0700	[thread overview]
Message-ID: <1459231593-360-16-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1459231593-360-1-git-send-email-bjorn.andersson-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>

From: Jason Mobarak <jam-W/OLz77bvjtBDgjK7y7TUQ@public.gmane.org>

Patch "wcn36xx: Pad TIM PVM if needed" has caused a regression in mesh
beaconing.  The field tim_off is always 0 for mesh mode, and thus
pvm_len (referring to the TIM length field) and pad are both incorrectly
calculated.  Thus, msg_body.beacon_length is incorrectly calculated for
mesh mode. Fix this.
