These patches improve statistics update as well as
endian conversion. Some of them appear to be suitable
for earlier kernel versions but I want to have them
well cooked in 3.14.
Amitkumar Karwar (5):
mwifiex: declare snap_type as __be16 variable
mwifiex: remove rfc1042_eth_hdr variable
mwifiex: fix an issue with Appletalk devices
mwifiex: remove redundant goto exit_remove statement
mwifiex: improvements in mwifiex_ret_tx_power_cfg()
Bing Zhao (1):
mwifiex: avoid using variable name eth_hdr
Ujjal Roy (6):
mwifiex: use little-endian variables in firmware structures
mwifiex: fix rx_pending count imbalance
mwifiex: correct RX byte count statistics
mwifiex: correct TX byte count statistics
mwifiex: update statistics for bridged packets on AP interface
mwifiex: do not flood kmsg/dmesg with USB debug messages

1.8.2.3
From: Amitkumar Karwar <[email protected]>
SNAP/LLC header in the AARP packet is being stripped off while
preparing an EthernetII header.
Annex M, Table M.3 in 802.11 spec says that some header
(ex. AppleTalk AARP(2)) should pass through untouched.
This patch modifies the check to exclude/include EthernetII
header translation for special cases.

Actually we are updating snap_type with h_proto (__be16 variable)
in ethernet frame header. Hence endianness conversion is not
required.

When TX data URB reaches high water mark the message
"data: -ENOSR is returned" is printed.
This is not an error case, so change it to debug print.
