+Subject: [PATCH] net: phy: broadcom: rehook BCM54612E specific init
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This extra BCM54612E code in PHY driver isn't really aneg specific. Even
+without it aneg works OK but the problem is no packets pass through PHY.
+
+Moreover putting this code inside config_aneg callback didn't allow
+resuming PHY correctly. When driver called phy_stop and phy_start it was
+putting PHY machine into RESUMING state. After that machine was
+switching into AN and NOLINK without ever calling phy_start_aneg. This
+prevented this extra setup from being called and PHY didn't work.
+
+This change has been verified to fix network on BCM47186B0 SoC device
+with BCM54612E.
