Update the PS mode of each link according to a bitmap polled from
fw_status. Manually notify mac80211 about PS mode changes in connected
stations.

mac80211 will only be notified about PS start when the station is in PS
and there is a small number of TX blocks from this link ready in HW.
This is required for waking up the remote station since the TIM is
updated entirely by FW.

When a station enters mac80211-PS-mode, we drop all the skbs in the
low-level TX queues belonging to this sta with STAT_TX_FILTERED
to keep our queues clean.

This patch reduces the rate of the null-func used to enter PSM on the last

Currently the PSM entry function assumes successful operation, and enables
ELP, BET and beacon filtering right away. This is bad, because the PSM
entry may fail due to environmental issues, which will cause the ELP, BET and
beacon filtering to be illegally enabled (because FW remains in active state.)

Fix this by enabling ELP, BET and beacon filtering only after successful entry,
and by ensuring the firmware is in active mode after the failure.

Implement delayed entry into ELP. This will promote the following:
 - Less redundant sleep/wake cycles (better perf)
 - Avoids known firmware issues with going to ELP too fast after an
   operation

This driver supports the wl1271 chipset from Texas Instruments based on the
WiLink(tm) 6.0 mobile platform.  Support for wl1273 should be relatively easy
to add.  This chipset is designed for embedded devices, with good powersaving
capabilities.  The wl1271 chipset is the successor of wl1251 and supports the
802.11b/g/n standards, but currently this driver supports only b/g.

More information about this chipset can be found here:

wl12xx is a driver for TI wl1251 802.11 chipset designed for embedded
devices, supporting both SDIO and SPI busses. Currently the driver
supports only SPI. Adding support 1253 (the 5 GHz version) should be
relatively easy. More information here:

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
