Use common ath key management functions in ath5k. This fixes problems with HW encryption in AP mode, which was broken in the ath5k implementation. Before (with the ath5k implementation) only one client could connect to the AP using HW encryption and WPA. When a second client connected, the first client was not able to send/receive any more packets. Because of the problems with HW encryption, software encryption was always used in AP mode, which resulted in a high CPU load (and/or low thruput) on embedded devices. Instead of trying to fix the implementation in ath5k it makes more sense to share the code with ath9k. This also enables HW encryption for AP mode again.

Copied the key cache management functions from ath9k (common.c and hw.c) to ath/key.c so we can use them from ath5k, later. Minor changes have been made: - renamed ath9k_* to ath_* - replaced ah->caps.keycache_size with common->keymax - removed ATH9K_IS_MIC_ENABLED since it is always true. - the AR_PCU_MIC_NEW_LOC_ENA flag is replaced with (splitmic == 0).

At the time the .add_interface driver op is called, the interface has not been marked as running yet, so ieee80211_iterate_active_interfaces will not pass it to the iterator function. Because of this, the calculated BSSID mask is wrong, which breaks multi-BSS operation. Additionally, the current way of comparing all addresses against each other is pointless, as the hardware only uses the hardware MAC address and the BSSID mask for matching the destination address, so all the address array reallocation is completely unnecessary. This patch simplifies the logic by setting the initial mask bytes to 0xff and removing all bits in the iterator call that don't match the hardware MAC address. It also calls the iterator for the vif that was passed to add_interface() Signed-off-by: NFelix Fietkau <nbd@openwrt.org> Tested-by: NBen Greear <greearb@candelatech.com> Signed-off-by: NJohn W.

The CPU consumption during the scan period is high, since the register write go over Interrupt endpoint. On downloading the firmware to the target, the USB descriptors are 'patched' to change the type of the endpoints from Interrupt to Bulk.

Since on timeout version of iwl_scan_cancel procedure we can sleep, do not have to schedule abort_scan work to begin and perform scanning, can do this directly. Also now, as we do not queue abort_scan from restart work anymore, we can queue abort_scan to priv->workqueue. Don't drop mutex when waiting for scan complete. Use STATUS_HW_SCAN bit to check if scanning is currently pending, because STATUS_SCANNING will be cleared only with priv->mutex taken.

Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values.

The test if antenna diversity is at all enabled uses a local variable 'flags' to prepare the test condition, but uses 'ant->flags' when the test is evaluated. The effect is that the diversity evaluation will never start. I can see two solutions, use the 'flag' in the test condition or revert the local flag change. My attached patch took alternative two. Then the evaluation start but it will still not switch antenna. The problem is a code section in rt2x00lib_config_antenna (). The effect of that code section is that any change the diversity function perform will be effectively shorten and no antenna selection command issued.
