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