    rt2x00: Don't let mac80211 send a BAR when an AMPDU subframe fails

To fix problem workaround by above commit use
IEEE80211_HW_TEARDOWN_AGGR_ON_BAR_FAIL flag (see change log for
"mac80211: introduce IEEE80211_HW_TEARDOWN_AGGR_ON_BAR_FAIL" patch).

rt2x00: Only specify interface combinations if more then one interface is possible

2013-01-17T16:45:44+00:00

commit f5685ba675449b072feab6a5391a9ef9f604bc94 upstream.

Otherwise rt2500* triggers a warning in cfg80211, from net/wireless/core.c:

	/* Combinations with just one interface aren't real */
	if (WARN_ON(c->max_interfaces < 2))

This was introduced in commit 55d2e9da744ba11eae900b4bfc2da72eace3c1e1:
rt2x00: Replace open coded interface checking with interface combinations.

rt2800: validate step value for temperature compensation

2012-10-30T19:58:54+00:00

Some hardware has correct (!= 0xff) value of tssi_bounds[4] in the
EEPROM, but step is equal to 0xff. This results on ridiculous delta
calculations and completely broke TX power settings.

rt2x00: usb: fix reset resume

2012-10-24T17:18:07+00:00

Patch fixes warnings like below happened on resume:

WARNING: at net/mac80211/driver-ops.h:12 check_sdata_in_driver+0x32/0x34()

Problem is that in __ieee80211_susped() we remove sdata (i.e wlan0
interface) and then during resume we call usb_unbind_interface() ->
ieee80211_unregister_hw() with sdata removed.

Patch fixes problem by adding .reset_resume calback, hence we do not
unbind usb device on resume. This callback can be the same as normal
.resume callback, sice we do all needed initalization during interface
start, which is performed on resume [ ieee80211_resume() ->
ieee80211_reconfig() -> rt2x00mac_start() -> rt2x00lib_start ].

rt2x00/rt3352: Fix lnagain assignment to use register 66.

2012-10-05T20:26:18+00:00

This should be register 66 instead of 62.

rt2x00: Replace open coded interface checking with interface combinations.

2012-09-25T19:57:44+00:00

Mac80211 has formal infrastructure to specify which interface combinations
are supported. Make use of this facility in favor of open coding it
ourselves.
So far we only have to specify we can support multiple AP interfaces,
no other combinations are supported.

Inspired by an earlier patch from Paul Fertser.

rt2x00: Deprecate max_sta_intf field of struct rt2x00_ops.

2012-09-25T19:57:43+00:00

All drivers set this value to 1, so there is no need (currently) to let
drivers set this.
Therefor, remove the field; we can always add it back when it is needed.

Move RT3290 BBP initialization sequence (part) to the right place in the code.

This is just a code style change, no functional changes.
