+Subject: [PATCH 3/3] net: bgmac: use PHY subsystem for initializing PHY
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds support for using bgmac with PHYs supported by standalone PHY
+drivers. Having any PHY initialization in bgmac is hacky and shouldn't
+be extended but rather removed if anyone has hardware to test it.
