There were a number of issues in the existing tx power handling code: 1. The EEPROM target power for chain 0 refers to the actual output power after the channel and bandwidth delta have been added to the initial channel gain. This means the delta values should not be added/subtracted for the rate power calculation 2. When power is reduced significantly, the initial channel gain underflows very quickly, while the per-rate power offsets are high. This miscalculation causes effective tx power to be increased when it should actually be lowered. Fix this by trying to adjust the channel gain to the lowest power from the rate table. In case of under- or overflow, compensate by adding an appropriate delta to the rate power values. This makes power configuration more accurate on a wider range of configurable values Signed-off-by: Felix Fietkau <nbd@nbd.name> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

The issue here is that we allocate "data" and then set "data = PTR_ALIGN(data, 8);" and then we free the aligned pointer instead of the original pointer. kmalloc() pointers are already ARCH_SLAB_MINALIGN aligned which is 8 or more on everything except certain Xtensa variants.

To support roaming below changes are done: * Station notify frame is send to firmware after sending assoc request. This will avoid dropping of first EAPOL frame due to delay in creation of station control block in firmware. * Data queues are unblocked after sending station notify in open mode, after configuring key in WEP mode, and after receiving EAPOL4 confirm in WPA mode. * Initial EAPOL frames priority is chaged to MGMT, rekey EAPOL frames priority changed to VO.
