Subject: [PATCH net-next v2 03/18] net: stmmac: dwmac1000: Add MAC loopback support
Date: Fri, 24 May 2019 10:20:11 +0200 [thread overview]
Message-ID: <c6cd496175260f6188051979992598b3e4906ac4.1558685827.git.joabreu@synopsys.com> (raw)

In-Reply-To: <cover.1558685827.git.joabreu@synopsys.com>
In preparation for the addition of stmmac selftests we implement the MAC
loopback callback in dwmac1000 core.
