+Subject: [PATCH] bgmac: fix MAC soft-reset bit for corerev > 4
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Only core revisions older than 4 use BGMAC_CMDCFG_SR_REV0. This mainly
+fixes support for BCM4708A0KF SoCs with Ethernet core rev 5 (it means
+only some devices as most of BCM4708A0KF-s got core rev 4).
+This was tested for regressions on BCM47094 which doesn't seem to care
+which bit gets used.
