* be2net: add multiple RX queue supportSathya Perla2010-10-04
| | | | | | | | | This patch adds multiple RX queue support to be2net. There are upto 4 extra rx-queues per port into which TCP/UDP traffic can be hashed into. Some of the ethtool stats are now displayed on a per queue basis. Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | * iwl3945: queue the right work if the scan needs to be abortedFlorian Mickler2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iwl3945's scan_completed calls into the mac80211 stack which triggers a warn on if there is no scan outstanding. This can be avoided by not calling scan_completed but abort_scan in iwl3945_request_scan in the done: branch of the function which is used as an error out. The done: branch seems to be an error-out branch, as, for example, if iwl_is_ready(priv) returns false the done: branch is executed. NOTE: I'm not familiar with the driver at all. I just quickly scanned as a reaction to https://bugzilla.kernel.org/show_bug.cgi?id=17722 the users of scan_completed in the iwl3945 driver and noted the odd discrepancy between the comment above this instance and the comment in mac80211 scan_completed function.

| | * | mac80211: Fix WMM driver queue configurationJuuso Oikarinen2010-09-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The WMM parameter configuration function (ieee80211_sta_wmm_params) only configures the WMM parameters to the driver is the wmm_last_param_set counter value is changed by the AP. The wmm_last_param_set is initialized to -1 on association in order to ensure the configuration is made to the driver at least once on association, but currently this initialization is done *after* the WMM parameter configuration function was called. This leads to unreliability in the driver getting properly configured on first association (depending on what counter value the AP happens to use.) When disassociating (the wmm default parameters are configured to the driver) and then reassociating, due to the above the WMM configuration is not set to the driver at all. On drivers without beacon filtering the problem is corrected by later beacons, but on drivers with beacon filtering the WMM will remain permanently incorrectly configured. Fix this by moving the initialization of wmm_last_param_set to -1 before ieee80211_sta_wmm_params is called on association.

| | * | mac80211: fix offchannel assumption upon associationLuis R. Rodriguez2010-09-28

When we do get the associatin response though we were never clearing the offchannel state. This has a few implications, we told drivers we were still offchannel, and the first configured TX power for the channel does not take into account any power constraints. For ath9k this meant ANI calibration would not start upon association, and we'd have to wait until the first bgscan to be triggered. There may be other issues this resolves but I'm too lazy to comb the code to check.

The patch not only broke the optimisation, it also introduced a bug: under some (common!) circumstances the flag will be set on an already freed skb! However, investigating this in more detail, I found that most of the flags that we set should be per packet, _except_ for this one, due to a-MPDU processing. Additionally, the flags used for processing (currently just this one) need to be reset before processing a new packet. Since we haven't actually seen bugs reported as a result of the wrong flags handling (which is not too surprising -- the only real bug case I can come up with is an a-MSDU contained in an a-MPDU), I'll make a different fix for rc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even if the reorder timeout timer fires while scanning, the frames weren't received during scanning and therefore shouldn't be dropped. To implement this, changes to the passive scan RX handler simplify understanding it, because it currently checks HW_SCANNING independently of a packet's in-scan receive status (which doesn't make a big difference, since scan_rx() will only pick up probe responses and beacons, which can't be aggregated.)

| | * | airo: remove "basic_rate" module optionDan Carpenter2010-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "basic_rate" module option is not implemented correctly. If the rate was set to zero it was supposed to set it to "basic_rate | 0x80". Unfortunately the check to see if what zero was wrong and it checked "!ai->config.rates" (which is always false) instead of "!ai->config.rates[i]". This option was just used for development and it wasn't documented anywhere. Instead of fixing it, we can just remove it.

| | * | mac80211: Add DS Parameter Set into Probe Request on 2.4 GHzJouni Malinen2010-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IEEE Std 802.11k-2008 added DS Parameter Set information element into Probe Request frames as an optional information on 2.4 GHz band (and mandatory, if radio measurements are enabled). This allows APs to filter out Probe Request frames that may be received from neighboring overlapping channels and by doing so, reduce the number of unnecessary frames in the air. Make mac80211 add this IE into Probe Request frames whenever the channel is known (i.e., whenever hwscan is not used).

Additionally, moving it there has effectively discarded the optimisation -- since the bit is only ever set on freed SKBs, and those were a copy, it could never be checked. For the current release, fixing this properly is a bit too involved, so let's just remove the problematic code and leave userspace with one copy of each frame for each virtual interface.

It enables qeth to receive priority-tagged frames on a base interface, for example from z/OS, without configuring an additional VLAN interface.

But actually, the called function init_sram can only return 0, so there is no need for the error check at all. init_sram is also given a void return type, and its single return statement at the end of the function is dropped. A simplified version of the sematic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ @r@ statement S1,S2,S3; constant C1,C2,C3; @@ *if (...) {...
