[PATCH 3.10 079/173] mwifiex: correct packet length for packets from SDIO interface

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Avinash Patil <patila@xxxxxxxxxxx>

commit d03b4aa77e1187b77dfe37d14a923547f00baa66 upstream.

While receiving a packet on SDIO interface, we allocate skb with
size multiple of SDIO block size. We need to resize this skb
after RX using packet length from RX header.
