2010-04-26ssb: do not read SPROM if it does not existJohn W. Linville3-0/+21
Attempting to read registers that don't exist on the SSB bus can cause hangs on some boxes. At least some b43 devices are 'in the wild' that don't have SPROMs at all. When the SSB bus support loads, it attempts to read these (non-existant) SPROMs and causes hard hangs on the box -- no console output, etc. This patch adds some intelligence to determine whether or not the SPROM is present before attempting to read it. This avoids those hard hangs on those devices with no SPROM attached to their SSB bus. The SSB-attached devices (e.g. b43, et al.) won't work, but at least the box will survive to test further patches. :-) Signed-off-by: John W.

2010-04-20ath9k: Group Key fix for VAPsDaniel Yingqiang Ma1-3/+25
When I set up multiple VAPs with ath9k, I encountered an issue that the traffic may be lost after a while. The detailed phenomenon is 1. After a while the clients connected to one of these VAPs will get into a state that no broadcast/multicast packets can be transfered successfully while the unicast packets can be transfered normally. 2. Minutes latter the unitcast packets transfer will fail as well, because the ARP entry is expired and it can't be freshed due to the broadcast trouble. It's caused by the group key overwritten and someone discussed this issue in ath9k-devel maillist before, but haven't work out a fix yet. I referred the method in madwifi, and made a patch for ath9k. The method is to set the high bit of the sender(AP)'s address, and associated that mac and the group key. It requires the hardware supports multicast frame key search. It seems true for AR9160. Not sure whether it's the correct way to fix this issue. But it seems to work in my test. The patch is attached, feel free to revise it.

Single/Dual stream mask are used to indicate the best antenna for SISO/MIMO; different NIC has different tx antenna configuration; so the parameter need to based on the valid tx antenna. 1x2 device: single tx antenna available, only SISO is valid configuration, but still need to set up MIMO configuration, so set it up with antenna A & B as default. 2x2 device: two tx antenna available, dual_stream will use both valid antenna. 3x3 device: three tx antenna available, skip the first antenna and choice the second and third antenna for dual_stream.
