If the radio enable switch is off when the driver is loaded, it is not possible to get radio output until the driver is unloaded and reloaded with the switch on. Signed-off-by:

rndis_set_default_key did call add_wep_key to set default key on device, even if key is WPA. This caused rndis_wlan not work with wpa_supplicant in nl80211 mode (causing disconnect from AP). Signed-off-by:

Sometimes device returns wrong number of items in bssid-list. Appears that some specific beacons trigger this problem and leads to very poor scanning results. Workaround by ignoring num_items received from device and walkthrough full bssid-list buffer. v2: Fix buffer range checks and reading next item length. Old code read behind buffer on last item but didn't use those values as 'count' would also reach zero. Also fix resizing of buffer if device has larger buffer, old code assumed that BSSID-list OID would return same buffer size when it really can return yet another new larger length.

The size of the eeprom data is 1088 bytes for AR9485. But a sanity check is done against 4K which would result in a 'potential read past the end of the buffer' smatch complaint. Reported-by:

Introduce a helper function to get the EEPROM mode from channel and remove multiple similar switch statements. Also since it's now easy to get the EEPROM mode from the channel, use them inside the functions which need it, instead of passing a redundant ee_mode parameter. Signed-off-by:

Add a new variable to keep track of the currently configured tx power. Before max_pwr was re-used for keeping the maximum allowed power as well as the current configuration. Doing a min() on it allows you to lower the txpower, but how would you be able to make it higher again? This patch fixes that by adding a new variable ah_cur_pwr which is used instead of txp_max_pwr to keep the current configuration. txp_max_pwr is used to check if we are within the limits. Another problem fixed by this patch is that it avoids setting a zero txpower when things are initialized first and the current power is not yet set. Signed-off-by:

ath9k supports its own set of virtual wiphys, and it uses the mac80211 idle notifications to know when a device needs to be idle or not. We recently changed ath9k to force idle on driver stop() and on resume but forgot to take into account ath9k's own virtual wiphy idle states. These are used internally by ath9k to check if the device's radio should be powered down on each idle call. Without this change its possible that the device could have been forced off but the virtual wiphy idle was left on.

The commit "ath9k_hw: warn if we cannot change the power to the chip" introduced a new warning to indicate chip powerup failures, but this is not required for devices that have been removed. Handle USB device removal properly by checking for unplugged status. For PCI devices, this warning will still be seen when the card is pulled out, not sure how to check for card removal.

These drivers share one header file, but nothing else. Worse, both drivers use the rtl8225 part with different register settings. The results has been some ugly naming -- let's simplify that. Signed-off-by:

Restricting the chainmask to 1 for legacy mode disables useful features such as MRC, and it reduces the available transmit power. I can't think of a good reason to do this in legacy mode, so let's just get rid of that code. Signed-off-by:

The commit 'ath9k_hw: Disable PAPRD for rates with low Tx power' changed the code that sets the PAPRD rate masks to use only either the HT20 mask or the HT40 mask. This is wrong, as the hardware can still use HT20 rates even when configured for HT40, and the operating channel mode does not affect PAPRD operation. The register for the HT40 rate mask is applied as a mask on top of the other registers to selectively disable PAPRD for specific rates on HT40 packets only. This patch changes the code back to the old behavior which matches the intended use of these registers. While with current cards this should not make any practical difference (according to Atheros, the HT20 and HT40 mask should always be equal), it is more correct that way, and maybe the HT40 mask will be used for some rare corner cases in the future.

When an skb is shared, it needs to be duplicated, along with its data buffer. If the skb does not have enough headroom, using skb_copy might cause the data buffer to be copied twice (once by skb_copy and once by pskb_expand_head). Fix this by using skb_clone initially and letting ieee80211_skb_resize sort out the rest. Signed-off-by:
