mac80211: add vht cap decode to debugfs

2016-05-31T11:07:54+00:00

This makes it a lot easier to understand the capabilities used
by the station:

VHT supported
cap: 0x300819b2
		MAX-MPDU-11454
		80Mhz
		RXLDPC
		SHORT-GI-80
		TXSTBC
		RXSTBC_1
		SU-BEAMFORMER-CAPABLE
		SU-BEAMFORMEE-CAPABLE
		BEAMFORMEE-STS: 0x0
		SOUNDING-DIMENSIONS: 0x0
		MU-BEAMFORMER-CAPABLE
		MPDU-LENGTH-EXPONENT: 0x0
		LINK-ADAPTATION-VHT-MRQ-MFB: 0x0
		RX-ANTENNA-PATTERN
		TX-ANTENNA-PATTERN
RX MCS: fffe
TX MCS: fffe

mac80211: clean up station flags debugfs

2016-04-05T10:12:26+00:00

Avoid the really strange %s%s%s expression, use an array
of flag names and check that all flags are present.

mac80211: remove sta_info debugfs sub-struct

2016-04-05T09:59:05+00:00

Since the previous patch, the struct only has a single member,
so remove the struct and leave just the single member.

mac80211: Remove unused variable in per STA debugfs struct

2016-04-05T09:57:11+00:00

Remove unused variable in per STA debugfs structure, 'commit 34e895075e21
("mac80211: allow station add/remove to sleep")' removed the only user of
'add_has_run'.

mac80211: enable starting BA session with custom timeout

2016-04-05T09:46:05+00:00

Currently the debugfs entry for starting aggregation session
starts it with timeout of 5 seconds. Allow opening a session
with a custom timeout (according to spec 0 is no timeout).
while at it, refactor the function and remove the magic numbers.

mac80211: move station statistics into sub-structs

2015-10-21T08:08:22+00:00

Group station statistics by where they're (mostly) updated
(TX, RX and TX-status) and group them into sub-structs of
the struct sta_info.

Also rename the variables since the grouping now makes it
obvious where they belong.

This makes it easier to identify where the statistics are
updated in the code, and thus easier to think about them.

mac80211: remove sta->last_ack_signal

2015-10-21T08:08:21+00:00

This file only feeds a debugfs file that isn't very useful, so remove
it. If necessary, we can add other ways to get this information, for
example in the NL80211_CMD_PROBE_CLIENT response.

mac80211: clean up station debugfs

2015-05-05T12:21:55+00:00

Remove items that can be retrieved through nl80211. This also
removes two items (tx_packets and tx_bytes) where only the VO
counter was exposed since they are split up per AC but in the
debugfs file only the first AC was shown.

Also remove the useless "dev" file - the stations have long
been in a sub-directory of the netdev so there's no need for
that any more.

mac80211: remove sta->tx_fragments counter

2015-05-05T12:21:55+00:00

This counter is unsafe with concurrent TX and is only exposed
through debugfs and ethtool. Instead of trying to fix it just
remove it for now, if it's really needed then it should be
exposed through nl80211 and in a way that drivers that do the
fragmentation in the device could support it as well.

mac80211: remove TX latency measurement code

2015-02-28T20:31:11+00:00

Revert commit ad38bfc916da ("mac80211: Tx frame latency statistics")
(along with some follow-up fixes).

This code turned out not to be as useful in the current form as we
thought, and we've internally hacked it up more, but that's not
very suitable for upstream (for now), and we might just do that
with tracing instead.

Therefore, for now at least, remove this code. We might also need
to use the skb->tstamp field for the TCP performance issue, which
is more important than the debugging.
