Fix some bugs reported by QC, and continue to submit btcoex patches for
further use.
v2: add my sob to commit log if missing, and remove trivial comments.
Ping-Ke Shih (8):
rtlwifi: Use mutex to replace spin_lock to protect IPS and LPS
rtlwifi: fix scan channel 1 fail after IPS
rtlwifi: Add sta_statistics of mac80211's op, and set filled=0 by
default
rtlwifi: enable mac80211 fast-tx support
rtlwifi: btcoex: Add power_on_setting routine
rtlwifi: btcoex: Remove global variables from btcoex
rtlwifi: btcoex: Add common function for qeurying BT information
rtlwifi: btcoex: add rfe_type parameter to btcoex
Steven Ting (1):
rtlwifi: Support A-MSDU in A-MPDU capability
Tsang-Shian Lin (1):
rtlwifi: unlink bss when un-association

Enter/leavel IPS and LPS are large critical section, and they can't use
sleep function because running in atomic-context, which own a spin_lock.
In commit ba9f93f82aba ("rtlwifi: Fix enter/exit power_save"), it moves
LPS functions to thread-context, so this commit can simply change LPS's
spin lock to mutex.
Considering IPS functions, rtl_ips_nic_on() may be called by TX tasklet
(softirq-context) that check whether packet is auth frame. Fortunately,
current mac80211 will ask driver to leave IPS using op_config with
changed flag IEEE80211_CONF_CHANGE_IDLE, before issuing auth frame, so
IPS functions can run in thread-context and use mutex to protect critical
section, too.
Also, this commit removes some useless spin locks.

If there is no connection, driver will enter IPS state. Meanwhile, it
fails to scan channel 1 by the command 'iw dev wlan0 scan freq 2412',
because hardware channel setting lose after IPS. Thus, restore channel
setting from hw->conf.channel set by last rtl_op_config().

When using iwconfig to check wifi status, wext uses 'static struct' of
sinfo to get station info so sinfo->filled will be persistent. Since the
commit 2b9a7e1bac24 ("mac80211: allow drivers to provide most station
statistics") assumes driver initializes sinfo->filled to declare supported
fields, without initialization it will report wrong info. This commit
simply set 'filled' to be zero simply, and left sinfo to be filled by
mac80211.

To enable the mac80211 fast-tx feature, the hw/driver needs to support
dynamic power saving and fragmentation. Since our driver does not
need to fragment packet into smaller pieces, we just hook an empty
callback of set_frag_threshold to avoid fragmentation in mac80211.
After this, the mac80211 will not fragment the packets and can transmit
them faster by cache the header information.

Once you have returned false for 8812, you do not need the 'else'. Use a simple

Of course, until HP starts encoding efuse correctly, the special ant_sel code is
still needed.

Adding an empty op like that feels pointless, IMHO (but without checking
mac80211 sources) not having the op should be the same as filled = 0. To
me this smells like a bug in mac80211.
Johannes, what do you think?

This also looks fishy, I guess there's a good reason why mac80211
requires set_frag_threshold()? To me this is just a workaround for a
mac80211 test.

But I can't really take that :( Typedefs are not really liked in
upstream and just makes code harder to read.

Kalle,
Overnight, I had prepared a patch to remove the typedefs. I have now respun it
to handle only the old ones. As the merge of this new patch needs to be
coordinated with PK's patches, I have sent it to him so that he can include it
with v3 of his series.

When I saw this flying by I had the same feeling. This is clearly not
how it was intended although you could interpret the comments of the
.set_frag_threshold() callback and IEEE80211_HW_SUPPORTS_TX_FRAG.
However, the fragmentation threshold is a user-configurable stack
parameter as per the standard. This patch effectively kill that option
for the user although there may be RF conditions in which fragmentation
can help. Having the user configure a fragmentation threshold of 2346
also disables fragmentation and allows mac80211 to use cached fastpath.
In short this should be NACK'ed.

Arend

Huh, this can't be right.

It can't be right. It would've broken each and every driver out there,
other than the one or two who implement this.
However, it looks like PK is actually correct - *wext* does appear to
be broken! nl80211 does this:
memset(&sinfo, 0, sizeof(sinfo));
err = rdev_dump_station(rdev, wdev->netdev, sta_idx,
mac_addr, &sinfo);
and
memset(&sinfo, 0, sizeof(sinfo));
...
err = rdev_get_station(rdev, dev, mac_addr, &sinfo);
and has a bug in cfg80211_cqm_rssi_update(). Wext also has bugs, I'll
send out a fix.

if (local->hw.wiphy->frag_threshold != (u32)-1 &&
!ieee80211_hw_check(&local->hw, SUPPORTS_TX_FRAG))
goto out;
so internally at least it has to be -1, does 2346 really do that?
remember, but it might well :-)

I am getting old. In my recollection the fragmentation threshold would
be set to maximum MPDU size, which I believed to be 2346. Not sure if
that still is true today. To be sure taken a look in the 2016 spec:
"""
dot11FragmentationThreshold OBJECT-TYPE
SYNTAX Unsigned32 (256..65535)
UNITS "octets"
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"This is a control variable.
It is written by an external management entity.
Changes take effect as soon as practical in the implementation.
This attribute specifies the maximum size of an individually addressed
MPDU beyond which the corresponding MSDU or MMPDU is fragmented, except
when an MSDU is transmitted under an HT-immediate or HT-delayed block ack
agreement, or when an MSDU is carried in an A-MSDU, or when an MSDU or
MMPDU is carried in an A-MPDU that does not contain a VHT single MPDU.
Fields added to the MPDU by security encapsulation are not counted against
the limit specified by this attribute. An MSDU or MMPDU might be
fragmented even if it is smaller."
DEFVAL { 65535 }
::= { dot11OperationEntry 5 }
"""
Anyway, the fact remains that we should leave it up to the user to
control the value.

Arend

I think the larger sizes are for 60 GHz.

But the point is that you *shouldn't* set SUPPORTS_TX_FRAG, and then
fast-xmit will only get used for non-fragmented setups, which
realistically is all anyone cares about anyway.
