+Subject: [PATCH] bgmac: increase rx ring size from 511 to 512
+
+Limiting it to 511 looks like a failed attempt at leaving one descriptor
+empty to allow the hardware to stop processing a buffer that has not
+been prepared yet. However, this doesn't work because this affects the
+total ring size as well
