Merge tag 'iwlwifi-next-for-john-2014-10-29' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next Emmanuel Grumbach <egrumbach@gmail.com> says: "The big new thing here is netdetect which allows the firmware to wake up the platform when a specific network is detected. Along with that I have fixes for d3 operation. The usual amount of rate scaling stuff - we now support STBC. The other commit that stands out is Johannes's work on devcoredump. He basically starts to use the standard infrastructure he built." Signed-off-by:

STBC is enabled on HT/VHT SISO rates in case we don't care about power consumption and it won't hurt BT. This is done only in case the peer and our chip support STBC of course. While at it fixed a bug which was causing bw and ldpc flags to be set incorrectly in the rate scale table in case we are switching to a legacy Tx column. This had no real impact. Signed-off-by:

Instead of checking if we are associated when suspending with wowlan enabled in the interface iterator, allow it to return an unassociated vif and move the check to the main suspend function. This will be needed by netdetect, since it should also work when we are not associated but the vif is active. Signed-off-by:

Take the WoWLAN handling code out of the main suspend function, dividing it into three parts: get_config (which is used before the firmware is switched), switch_to_d3 (which handles the rebooting of the hardware with the D3 firmware) and config (which configures the D3 firmware for WoWLAN operation). This is necessary to prepare for the net-detect implementation, which will use only the switch_to_d3 part of this flow. Signed-off-by:
