From 562db532760827f6ce30801a08e6b568848bc9f2 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 29 Apr 2010 07:41:53 -0700 Subject: iwlagn: wait for asynchronous firmware loading When we kick off a firmware loading process, and then unbind from the pci device right away, we get into trouble. Avoid that by waiting for the firmware loading to finish (whether successfully or not) before the unbind in iwl_pci_remove.

That leads to a bug with injection -- it is currently not possible to inject frames when the only virtual interface is a monitor, because in that the required broadcast station is missing. Additionally, allocating and deallocating the broadcast station's LQ all the time is wasteful, and the code to support this is fairly complex. So this changes completely the way we manage the broadcast station. Rather than manage it along with any interface, we now allocate it when we bring the device up, and remove it again when we bring the device down. When we bring the device up, we don't immediately program the broadcast station into it, instead we just mark it active and rely on the next restore cycle to upload it to the device. This works because an unassociated RXON is always required at least once to set up device parameters, which implies a reprogramming of stations into the device. As we now manage all stations properly, there no longer is a need for forcing a clearing of them via iwl_clear_ucode_stations(), which can become a lot simpler.

A consequence of that is that the driver will know that it is not communicating on HT anymore, but the rate scaling table is still under the impression it is operating in HT. Any time after driver has been notified channel is not HT anymore there will thus be a firmware SYSASSERT when the current active LQ command is sent. A workaround for this issue is to not send a LQ command in the short time between being notified channel is not HT anymore and rate scaling table being updated.

Remove iwl_get_sta_id() and use iwl_sta_id() instead as appropriate. This reduces the amount of code needed to find the right station significantly, and works since mac80211 passes the station only after it has been fully initialised, ie. even if TX races with station addition it will only be passed to TX once the addition is complete.

Also, instead of dropping them immediately though move the check *after* we check for all sort of frame errors. This should enable us to discard these frames if the hardware picks other bogus items first. Lets see if we still get those jumbo counters increasing still with this. Jumbo frames would happen if we tell hardware we can support a small 802.11 chunks of DMA'd frame, hardware would split RX'd frames into parts and we'd have to reconstruct them in software. This is done with USB due to the bulk size but with ath5k we already provide a good limit to hardware and this should not be happening. This is reported quite often and if it fills the logs then this needs to be addressed and to avoid spurious reports. Cc: stable@kernel.org Signed-off-by: Luis R. Rodriguez Signed-off-by: John W.

RANGE_OSDAC is set to 0x1 for 2G, 0x0 for 5G 2. offsetC1 is set to 0xc 3. inv_clk320_adc is set to 0x1 * To reduce PHY error(from spur), cycpwr_thr1 and cycpwr_thr1_ext are increased to 0x8 at 2G. * The 2G Rx gain tables are updated with mixer gain setting 3,1,0.

The handling of tx descriptors for beacons can be simplified by updating write_tx_desc implementations of each driver to write directly to the queue entry descriptor instead of to a provided memory area. This is also a preparation for further clean ups where descriptors are properly reserved in the skb instead of fiddling with the skb data pointer.
