Subject: [PATCH net-next v2 01/18] net: stmmac: Add MAC loopback callback to HWIF
Date: Fri, 24 May 2019 10:20:09 +0200	[thread overview]
Message-ID: <2a2ce669fe2456d6615a4f71d3c97312bb013a41.1558685827.git.joabreu@synopsys.com> (raw)
In-Reply-To: <cover.1558685827.git.joabreu@synopsys.com>
In-Reply-To: <cover.1558685827.git.joabreu@synopsys.com>

In preparation for the addition of selftests support for stmmac we add a
new callback to HWIF that can be used to set the controller in loopback
mode.
