2013-01-11mwifiex: update config_bands during infra associationAmitkumar Karwar
Currently "adapter->config_bands" is updated during infra association only if channel is provided by user in "iw connect" command. config_bands is used while preparing association request to calculate supported rates by intersecting our rates with the rates advertised by AP. There is corner case in which we include zero rates in supported rates TLV based on previous IBSS network history, which leads to association failure.

2012-11-26cfg80211: pass a channel definition structJohannes Berg
Instead of passing a channel pointer and channel type to all functions and driver methods, pass a new channel definition struct. Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change.

2012-11-26cfg80211: remove remain-on-channel channel typeJohannes Berg
As mwifiex (and mac80211 in the software case) are the only drivers actually implementing remain-on-channel with channel type, userspace can't be relying on it. This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

2012-11-14mwifiex: add multi-queue supportAvinash Patil
This patch adds support for multiple TX queues inside mwifiex driver. Four different queues according to WMM access categories are defined for each virtual interface. When a packet is received from netdev for transmission, tx pending count for particular queue is incremented and if tx pending count has reached upper water-mark, this queue is stopped instead of stopping all queues. Similarly when a packet is successfully transmitted from device, tx pending count is decremented per queue and if pending count falls below lower water-mark, queue operations are again resumed. This ensures that not all tranmission is blocked if traffic with particular TOS value suddenly increases. Also wake all queues after association/IBSS_join/uAP_BSS_start to enable traffic on all queues.

2012-10-30cfg80211: allow per interface TX power settingJohannes Berg
The TX power setting is currently per wiphy (hardware device) but with multi-channel capabilities that doesn't make much sense any more. Allow drivers (and mac80211) to advertise support for per-interface TX power configuration. When the TX power is configured for the wiphy, the wdev will be NULL and the driver can still handle that, but when a wdev is given the TX power can be set only for that wdev now.

This reverts commit 34202e28fe7fc8551313f9a035a8857db83de757 We made "34202ee.." because we didn't support custom regulatory rules at that time. But now we use our own custom regulatory rules, so it needs to be changed back. Also, chan->max_power calculations in cfg80211 were broken. Hence we started using chan->max_reg_power. Now it has got fixed in following commit. commit 5e31fc0815a4e2c72b1b495fe7a0d8f9bfb9e4b4 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Tue Jul 24 08:35:39 2012 +0200 wireless: reg: restore previous behaviour of chan->max_power calculations Hence we will use chan->max_power instead of chan->max_reg_power.
