YanBo 79617deeeb mac80211: mesh portal functionality support
Currently the mesh code doesn't support bridging mesh point interfaces
with wired ethernet or AP to construct an MPP or MAP. This patch adds
code to support the "6 address frame format packet" functionality to
mesh point interfaces. Now the mesh network can be used as backhaul
for end to end communication.

Johannes Berg 44d414dbff mac80211: move some HT code out of mlme.c
Some of the HT code in mlme.c is misplaced:
 * constants/definitions belong to the ieee80211.h header
 * code being used in other modes as well shouldn't be there

Harvey Harrison fd7c8a40b2 mac80211: add helpers for frame control testing
A few general categories:

1) ieee80211_has_* tests if particular fctl bits are set, the helpers are de
in the same order as the fctl defines:

A combined _has_a4 was also added to test when both FROMDS and TODS are set.

2) ieee80211_is_* is meant to test whether the frame control is of a certain
ftype - data, mgmt, ctl, and two special helpers _is_data_qos, _is_data_pres
which also test a subset of the stype space.

When testing for a particular stype applicable only to one ftype, functions
like ieee80211_is_ack have been added.  Note that the ftype is also being
checked in these helpers.  They have been added for all mgmt and ctl stypes
in the same order as the STYPE defines.

3) ieee80211_get_* is meant to take a struct ieee80211_hdr * and returns a
pointer to somewhere in the struct, see get_SA, get_DA, get_qos_ctl.

The intel wireless drivers had helpers that used this namespace, convert the
all to use the new helpers and remove the byteshifting as they were defined
in cpu-order rather than little-endian.

This patch allows to disable FAT channel in specific configurations.

For example the configuration (8, +1), (primary channel 8, extension
channel 12) isn't permitted in U.S., but (8, -1), (primary channel 8,
extension channel 4) is. When FAT channel configuration is not
permitted, FAT channel should be reported as not supported in the
capabilities of the HT IE in association request. And sssociation is
performed on 20Mhz channel.

Ron Rindjunsky edcdf8b21a mac80211: separate Tx and Rx MCS when configuring HT
This patch follows the 11n spec in separation between Tx and Rx MCS
capabilities. Up until now, when configuring the HT possible set of Tx
MCS only Rx MCS were considered, assuming they are the same as the Tx MCS.
This patch fixed this by looking at low level driver Tx capabilities.

Daniel Drake 5628221caf [PATCH] mac80211: ERP IE handling improvements
The "protection needed" flag is currently parsed out of the ERP IE in
beacons. This patch allows the ERP IE to be available at assocation time
and causes the appropriate actions to be performed earlier.

It is slightly complicated by the fact that most APs don't include the
ERP IE in association responses. To work around this, we store ERP
values in the ieee80211_sta_bss structure.

Also added some WLAN_ERP defines for use by upcoming patches.
