From: Franky Lin <[email protected]> Aborting the current read attempt on the superframe also removes the packet from the pipeline. Retries should not be attempted on the next packet since it would not be a superframe(either a superframe descriptor or other data packet) and should not be handled by brcmf_sdio_rxglom
