Subject: [PATCH v2 net-next 11/13] net: stmmac: Correctly assing MAX MTU in XGMAC cores case
Date: Wed, 4 Sep 2019 15:17:03 +0200 [thread overview]
Message-ID: <76deaf061fd37a1e46fd2ad59a0c83c56bc79de3.1567602868.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1567602867.git.joabreu@synopsys.com>
In-Reply-To: <cover.1567602867.git.joabreu@synopsys.com>
Maximum MTU for XGMAC cores is 16k thus the check for presence of XGMAC
shall be done first in order to assign correct value.
