2008-12-25forcedeth: don't poll NV event 36Johannes Berg
Polling doesn't seem to be necessary on my hardware, at least I haven't seen any bad effects testing it a while. Remove the polling so the CPU doesn't have to wake up a hundred times per second.

This patch removes the pci_bist and pci_hdr_type members from the device structure and removes the code that references them. They are not really used. The patch rounds out the changes by moving the pci_cmd member to plug a structure hole that would have been created. On 32-bit systems, this movement removes a subsequent structure hole later in the structure. On 64-bit systems though, the movement merely consolidates two holes into one larger hole.

2008-12-19ath9k: Fixed RX decryption status reportingJouni Malinen
The RX code in ath9k uses sc_keymap to figure out whether a default key was used. However, the default key entries in sc_keymap were always set and as such, frames could have been claimed to be decrypted by hardware when they were not. This can cause problems especially with TKIP since mac80211 is validating the Michael MIC in the frame and this will result in MIC failure and potentially TKIP countermeasures if the frame was not decrypted correctly. Change key cache slot allocation to mark only the keys that really have been used in sc_keymap to avoid the issue. The key cache slot selection routines are now internally avoiding the slots that may be needed for TKIP group keys. Signed-off-by: Jouni Malinen <jouni.malinen@atheros.com> Signed-off-by: John W.
