2009-05-11iwlagn: improve rate scale table searchMohamed Abbas
iwlagn rate scaling will periodically search other rate scale tables to switch to the best table regarding performance. In the past the number of search tables were 3. Every time the rate scale algorithm goes through these available tables in will stay in current table for some time before start searching again. Recent driver support more feature and antenna, so we have more tables to search. This patch make sure we go through all available tables.

2009-04-22iwlwifi: Display decoded rate/mcs informationWey-Yi Guy
This patch adding MCS information in rate_scale_table, it help for debugging rate scaling algorithm, easy to understand what is the current rate scale table and matching modulation, plus the last mcs used for tx.

2009-04-22iwlwifi: adding MIMO3 support in rate scalingWey-Yi Guy
Separated the MIMO tpt matrix into MIMO2 and MIMO3, adding MIMO3 support in rate scaling algorithm. If the device support 3x3, then utilize all three antenna (A/B/C) for tx to improve throughput. Adding rs_switch_to_mimo3() function to allow switch to mimo3 modulation mode from other modes(legacy/siso/mimo2). Adding rs_move_mimo3_to_other() function to allow switch from mimo3 modulation mode to either siso or mimo2; also support toggle between SGI and NGI.

2009-03-16iwlwifi: HT performance improvement changesWey-Yi Guy
During rate scaling, checking for 0 retry count before decrement the count by 1, this can avoid the retry count to become 255 (0xff), which will cause the rate to drop faster than what we expect during good condition (receive 0 retry packet). also change the algorithm to make the rate not drop faster than what we like.

2009-01-29iwl3945: Use iwl-agn-rs.h rates definitions.Samuel Ortiz
A lot of rate relates definition are shared between iwl-3945-rs.h and iwl-agn-rs.h. Let's just use the agn version, and add the 3945 specific constants there.
