Subject: [RESEND PATCH 15/16] wcn36xx: don't pad beacons for mesh
Date: Tue, 29 Mar 2016 14:41:12 -0700 [thread overview]
Message-ID: <1459287672-3324-1-git-send-email-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <1459231593-360-16-git-send-email-bjorn.andersson@linaro.org>
From: Jason Mobarak <jam@cozybit.com>
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.
