+Subject: [PATCH] bgmac: add helper checking for BCM4707 / BCM53018 chip id
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Chipsets with BCM4707 / BCM53018 ID require special handling at a few
+places in the code. It's likely there will be more IDs to check in the
+future. To simplify it add this trivial helper.
