* iwlwifi: mvm: Add support for Low Power RXAlexander Bondar2013-06-25
| | | | | | | | | | | | To improve power consumption in idle associated mode FW may lower RX power. This low linearity mode is acceptable for listening low rate RX such as beacons and groupcast. The driver enables LPRX only if PM is enabled and associated AP's beacon TX rate is 1Mbps or 6Mbps. LPRX RSSI threshold is used to limit a range where LPRX is applied.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since driver does not use control.rates[0].count, we have never set that variable. But currently, after rate control API rewrite, this is required by mac80211. Otherwise legacy rates control does not work and we transmit always at 1Mbit/s on pre 11n networks.

When the file is opened the D3 firmware is loaded and all regular commands are blocked. While the file is being read, poll the firmware's PME status flag and report EOF once it changes to non-zero. When it is closed, do (most of) the resume processing. This lets a user just "cat" the file. Pressing Ctrl-C to kill the cat process will resume the firwmare as though the platform resumed for non-wireless reason and when the firmware wants to wake up reading from the file automatically completes. Unlike in real suspend, only disable interrupts and don't reset the TX/RX hardware while in the test mode. This is a workaround for some interrupt problems that happen only when the PCIe link isn't fully reset (presumably by changing the PCI config space registers which the core PCI code does.) Note that while regular operations are blocked from sending commands to the firmware, they could still be made and cause strange mac80211 issues. Therefore, while using this testing feature you need to be careful to not try to disconnect, roam or similar, and will see warnings for such attempts. Als note that this requires an upcoming firmware change to tell the driver the location of the PME status flag in SRAM. D3 test will fail if the firmware doesn't report the pointer.
