Subject: [PATCH net-next 3/5] net: stmmac: dwmac4: Enable RX Jumbo frame support
Date: Fri, 6 Sep 2019 09:41:15 +0200 [thread overview]
Message-ID: <1eb3adcf838e92cffd2c4a6ef405fed0f3ac2b1e.1567755423.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1567755423.git.joabreu@synopsys.com>
In-Reply-To: <cover.1567755423.git.joabreu@synopsys.com>
We are already doing it by default in the TX path so we can also enable
Jumbo Frame support in the RX path independently of MTU value.
