Cover letter [PATCH 0/15] mac80211/iwlwifi (#everything): integrate IEEE802.11n support

This series of patches contains all 802.11n code + fixes of comments to the first two cycles of 802.11n patches.

Fixed list:
===========
- removing MAC80211_HT from config and all *.[ch] files
- removing IWL4965 config dependency on MAC80211_HT
- adding MAC80211_HT_DEBUG to config file and to relevant places
- refine TODO remark in ieee80211_sta_process_addba_request
- net_ratelimit() added to relevant prints
- renaming ieee80211_rx_h_data_agg to ieee80211_rx_h_amsdu
- removing parentheses from IEEE80211_CONF_SUPPORT_HT_MODE use
- changing amsdu_frame type from u16 to u8
- adding define SUPP_MCS_SET_LEN 16 to indicate MCS set length
- fixes to some typos
- Changes to Rx handlers PAE and drop unencrypted (for EAPOL frames in amsdu)

If this series is accepted then next series will contain the follow:

TODO list (planned for next series of patches)
==============================================
- Full A-MPDU aggregation capability.
- AP flows
- Examine config flows in mac80211 (RFC is prepered)

Notes to this series:
======================
This series of patches splits into two parts:
- patches 1-7 add 802.11n support to mac80211.
- patches 8-15 demonstrates the use of the above mac80211's 802.11n framework through iwl4965 low level driver

In order to be compatible with the 802.11n requirements for an HT station, patches 1-7 should not be treated as stand alone patches, but as a complete framework, although separation to patches by subjects was made for ease of handling. This applies to patches 8-15 as well.

The patches do _not_ break any existing driver.

patches were made (and tested to work) with wireless branch 2.6.24-rc3 (#everything)

The framework includes the following:
- HT probing.
- HT association.
- Support in Rx A-MSDU.
- Support in A-MPDU addBA request.
- HT information and configuration delivery to both low-level driver and rate scaling.
