| * iwmc3200wifi: Add a last_fw_err debugfs entrySamuel Ortiz2009-09-015-4/+113
| | | | | | | | | | | | | | | | In order to check what was the last fw error we got accross resets, we add this debugfs entry. It displays the complete ASSERT information. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
| * iwmc3200wifi: Handle UMAC stalls and UMAC assert properlySamuel Ortiz2009-09-013-9/+40
| | | | | | | | | | | | | | | | | | | | | | | | When UMAC stalls or asserts, we want to reset the device. But when we're associated, the current reset worker will end up calling cfg80211_connect_result() with the cfg80211 sme layer knowing that we're reassociating. That ends up with some ugly warnings. With this patch we're telling the upper layer that we've roamed if reassociation succeeds, and that we're disconnected if it fails.

| * iwmc3200wifi: New initial LMAC calibrationSamuel Ortiz2009-09-014-18/+61
| | | | | | | | | | | | | | | | | | | | | | The LMAC calibration API got broken mostly by having a configuration bitmap being different than the result one. This patch tries to address that issue by correctly running calibrations with the newest firmwares, and keeping a backward compatibility fallback path for older firmwares, where the configuration and result bitmaps were identical.

| * iwmc3200wifi: add disconnect workZhu Yi2009-09-013-5/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the driver receives "connection terminated" event from device, it could be caused by 2 reasons: the firmware is roaming or the connection is lost (AP disappears). For the former, an association complete event is supposed to come within 3 seconds. For the latter, the driver won't receive any event except the connection terminated. So we kick a delayed work (5*HZ) when we receive the connection terminated event. It will be canceled if it turns out to be a roaming event later. Otherwise we notify SME and userspace the disconnection. Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: John W.

| * rt2x00: Reorganize padding & L2 paddingIvo van Doorn2009-08-314-44/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old function rt2x00queue_payload_align() handled both adding and removing L2 padding and some basic frame alignment. The entire function was being abused because it had multiple functions and the header length argument was somtimes used to align the header instead of the payload. Additionally there was a bug when inserting L2 padding that only the payload was aligned but not the header. This happens when the header wasn't aligned properly by mac80211, but rt2x00lib only moves the payload. A secondary problem was that when removing L2 padding during TXdone or RX the skb wasn't resized to the proper size. Split the function into seperate functions each handling its task as it should.

| | | | | | | | | | | | | | | | | | | | | | | | Significant literature suggests users use debug flags 0x43fff - this causes the debug flags to be set that causes information to be printed for every received frame - including beacons. In the best case it fills up the logs, at worst it slows driver down and causes failures due to timeouts. In the RX handler, print debugging only if user requested RX debugging.

| * iwlwifi: use sleep interval successionJohannes Berg2009-08-311-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some concerns were raised about the automatic adjustment of sleep intervals to all the same, potentially high, value, and I can imagine the hardware behaving better when we don't ask too much of it. So let's convert to use a succession of sleep levels when requesting to go to deeper sleeps (which can only happen with large DTIM intervals), using the succession values from power level three, which have the benefit of also having been tested extensively already. As a result, the automatic sleep level adjustment will now be mostly equivalent to power level three, except for the RX/TX timeouts and possibly using smaller sleep vectors to account for networking latency.

| * iwlwifi: use iwl_hwrate_get_mac80211_idx where appropriateDaniel C Halperin2009-08-314-12/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For HT packets, mac80211 expects the rate_idx to be an MCS number, which is the lower byte of rate_n_flags. However, iwl_hwrate_to_plcp_idx takes the MCS number and reduces it down to the range 0-8 (6 to 60 Mbps), removing the bits that signify multiply streams, HT40 Duplicate mode, or unequal modulation. This version is used for various internal purposes through the driver. Add the function iwl_hwrate_get_mac80211_idx, an alternate version which takes the rate and the band and returns the mac80211 index (MCS, for HT packets, and PLCP rate, for legacy packets).

| * iwlwifi: remove incorrect uses of ieee80211_get_tx_rate to prevent TX stallDaniel C Halperin2009-08-311-49/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor and correct rate selection for outgoing transmitted packets. First, note that HT rates in the mac80211 rate table do not provide valid indices when ieee80211_get_tx_rate is called; the check to see if we could to abort a transmission early in iwl_tx_skb() would thus occasionally read invalid memory and occasionally stall transmission (if the erroneous byte was 0xff). We remove that code; the check wasn't valid anyway. Second, iwl_tx_cmd_build_rate() also called ieee80211_get_tx_rate to be used for sending management packets, which do not use the uCode station table. This patch refactors that function and adds comments to enhance legibility, replaces the call to ieee80211_get_tx_rate() with a direct lookup, and adds error handling in case the table entry is invalid.
