* b43/legacy: Remove firmware IDsMichael Büsch2011-08-244-15/+2
| | | | | | | | | | | | This removes the "FWxx" ID strings from the b43 and b43legacy drivers. They were once used to match a specific driver revision to a set of firmware files. However, this is hardly useful today. Additionally, the IDs are not updated and maintained properly, so they might mislead users.

* ath9k_hw: Disable Walsh spatial spreading for 2 chainsRajkumar Manoharan2011-08-242-2/+2
| | | | | | | | | | | | | | The Walsh bit is disabled for regulatory consideration. FCC limit for walsh enable is lower than that for walsh disable. So disabling walsh bit will not limit tx power/affect tx power even in cases where we are not FCC limited (most client cards). If the tx power is not FCC limited, then enabling/disabling walsh bit will not affect Avg. EVM/overall performance in any visible manner.

* ath9k: Change rate control to use legacy rate as last MRRRajkumar Manoharan2011-08-241-7/+27
| | | | | | | | | | | | | | In congested network, having all rate reties at MCS rates is failing to transmit the frame offenly. By the time reaching the success rate set, the application gets timed out. One such scenario is that authentication time out during 4-Way handshake. This patch uses a legacy rate as last retry sequnce for unaggregated frames or if the first selected rate's PER is ~80% of max limit. And also observed from the tx status that the frame was trasmitted successfully by using legacy rates. Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.
