Subject: [PATCH v2 net-next 10/13] net: stmmac: xgmac: Correct RAVSEL field interpretation
Date: Wed, 4 Sep 2019 15:17:02 +0200 [thread overview]
Message-ID: <052fee54b53b4ea506019d7466f7fe25eeb1ad00.1567602868.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1567602867.git.joabreu@synopsys.com>
In-Reply-To: <cover.1567602867.git.joabreu@synopsys.com>
RAVSEL means that only RX side is available for AVB features. As we use
both TX and RX features we need to check if RAVSEL is selected and
disable AVB if only RX side is available.
