From 4ce7bc0a4e555f8519e1a2c8a8569f203bd5727c Mon Sep 17 00:00:00 2001 From: Zhaoyang Liu Date: Fri, 13 Feb 2015 20:38:16 +0530 Subject: [PATCH] mwifiex: fix usb tx data payload offset issue Commit 84b313b35f8158d7 ("mwifiex: make tx packet 64 byte DMA aligned") induced payload offset issue for USB interface. There is no USB interface header for tx packets, so there's no need to pull interface length while processing tx skb. This patch fixes this issue.
