   4 Subject: [PATCH] brcmfmac: fix sdio sending of large buffers.
   5
   6 the function brcmf_sdiod_ramrw is supposed to be able to send
   7 large blobs of data. However inside the loop the skb->len field
   8 did not correctly get reset each round. As a result only small
   9 blobs could be sent. This patch fixes this problem.
