From 68ac92e9378c3453c86de35df0b6700181f4393b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 21 Jan 2018 14:55:44 +0100 Subject: [PATCH] net: sh_eth: Separate out MAC address programming Pull out the code for writing MAC address into the NIC into a separate function, so it can be reused by both DM and non-DM code. This is done in preparation for DM support, which handles MAC address programming separately.
