2014-12-01wil6210: reset flow updateVladimir Kondratiev
If card reset with firmware download executed, followed by reset with use of firmware from build in flash, firmware download indication remains in the hardware register. When running firmware download flow, the SW download indication is written by the driver to bit 0 in usage_6: wil_fw_load(), "S(RGF_USER_USAGE_6, 1);" This register, like all USER RGF, wasn't reset in SW reset flow. Therefore the driver must clear it on SW reset flow. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2014-12-01wil6210: Rate limit "ring full" error messageVladimir Kondratiev
In the wil_tx_ring, error message printed when tx attempted while vring has no space to accommodate all fragments of frame. Normally, such situation handled by stopping tx queue. But, if tx queue is by-passed (like pktgen does), this error will be triggered at high rate and dmesg will be flooded with this message. Whole system may become unstable and hang with no possible recover except power cycle. Rate-limit it to prevent dmesg flooding.

2014-12-01wil6210: remove wil_to_pcie_dev()Vladimir Kondratiev
There is no need to obtain physical device through wil->pdev->dev path, as it is done by this macro. The same device already stored as wiphy's device, thus wil_to_dev() returns the same device as wil_to_pcie_dev() Remove unnecessary macros, this allows to drop dependency by pci.h in the firmware download code.

2014-12-01Revert "rt2x00: Endless loop on hub port power down"Stanislaw Gruszka
This reverts commit 2ad69ac5976191e9bb7dc4044204a504653ad1bb. It causes wireless device disappear when we get -EPROTO error form USB request. I encounter such situation occasionally when resume form suspend with RT3070 adapter: [ 289.619985] ieee80211 phy0: rt2x00usb_vendor_request: Error - Vendor Request 0x06 failed for offset 0x0404 with error -71 [ 289.639368] ieee80211 phy0: rt2800_wait_bbp_ready: Error - BBP register access failed, aborting [ 289.639374] ieee80211 phy0: rt2800usb_set_device_state: Error - Device failed to enter state 4 (-5) Without the patch, except printing error, device works just fine after resume. Currently after timeouts and REGISTER_BUSY_COUNT tuning, we should not have any "endless loop", though we can wait quite long when driver is trying to communicate with the device through non functioning USB connection. Generally the problem that commit 2ad69ac597619 solves is kinda artificial. Cc: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.

2014-12-01rt2800: calculate tx power temperature compensation on selected chipsStanislaw Gruszka
Currently implemented temperature compensation is only valid on some of supported chips. Other chips do not need temperature compensation or need different way to do this (not yet implemented in the rt2800 driver). Trying to do run rt2800_get_gain_calibration_delta() when this is not appropriate on particular chip gives bogus result of TX power and can make connection unstable. This is follow up to commit 8c8d2017ba25c510ddf093419048460db1109bc4 "rt2800: fix RT5390 & RT3290 TX power settings regression".
