[PATCH review for 3.18 02/12] staging: rtl8712u: Fix endian settings for structs describing network packets

["Levin, Alexander (Sasha Levin)" <alexander.levin@verizon.com>]

From: Larry Finger <Larry.Finger@lwfinger.net>

[ Upstream commit 221c46d28957bd6e2158abc2179ce4a8c9ce07d3 ]

The headers describing a number of network packets do not have the
correct endian settings for several types of data.
