This warning happens if DMA mapping/allocation returns a page that's not
page-aligned??
rxb->page_dma =
dma_map_page(trans->dev, page, rxb->offset,
trans_pcie->rx_buf_bytes,
DMA_FROM_DEVICE);
(or similar places), where rxb->offset will always be 0 unless
rx_buf_bytes is set to 2048, but that can only happen if the amsdu_size
module parameter is set to 4 (=2k) but that's not even supported any
more?
Maybe make this WARN_ONCE(...) with a string that has more info on the
addresses.
