Just some style trivia if you want to clean it up later.

It'd be nicer if you always used this wrapping style.

checkpatch wouldn't bleat a long line warning here if it was
written as:

		bgmac_warn(bgmac, "DMA TX ring 0x%X wasn't disabled on time, waiting additional 300us\n",
			   ring->mmio_base);

There are maybe a dozen lines like it.

Here's one.
This format is also missing "\n" newline termination.

			bgmac_err(bgmac, "Hardware reported transmission for empty TX ring slot %d! End of ring: %d\n",
				  ring->start, ring->end);
