Tuning rings size for performance optimization.
Increasing Tx ring size, allows buffering more packets for HW, thus
eliminating idle periods which were observed with smaller ring at
high throughput, because HW was fetching packets faster than driver was
filling them into the TX ring. Rx ring was similarly increased to
avoid same problems in Rx.

upon cfg80211_stop_ap, a graceful AP shutdown is requested from firmware
followed by firmware reset.
In case graceful request failed, error was returned to cfg80211.

The change is to return success in this scenario, because firmware
reset will anyhow shutdown the AP.

netif_carrier_on indication was too late. In case Rx packet received
before netif_carrier_on indication, upper layers could not send
Tx packet back.

The fix is to indicate netif_carrier_on earlier:
for STA, indicate netif_carrier_on when association starts.
for AP/PCP, indicate netif_carrier_on upon starting AP/PCP.

since ded220bd ("[STRING]: Move strcasecmp/strncasecmp to

been incremented to point to the terminating NUL bytes, so they would

* more work for new devices (4165 / 8260)
* cleanups / improvemnts in rate control
* fixes for TDLS
* major statistics work from Johannes - more to come
* improvements for the fw error dump infrastructure
* usual amount of small fixes here and there (scan, D0i3 etc...)

In the PHY_CTXT command sent to the FW the TX chains were
indeed configured by the values of both FW TLVs and of NVM,
but the RX chains were left out and configured only by FW
TLV.

This causes problems in 4165 HW, where there are 1x1
antennas, and the wrong configuration denies the driver
from connecting to the AP.
