This diff adds 11n support to the athn(4) driver.

Tested in hostap mode and client mode with:

Even though the 11n standard mandates MCS 0-15 for APs, some APs have config
knobs which disable a subset of MCS, and some admins do touch these knobs.
E.g. at 33C3 there are APs with: RxMCS 0xf8f8f800

This change allows iwm(4) users to see which rates they're sending and

To see rates in tcpdump you need to use -y and -v options.

I don't understand why this was added. Perhaps the assumption was

letting the hardware retry at lower rates seems to hurt at least my

Stop using RTS for every data frame sent by iwm(4).
RTS adds unneccessary overhead if small data frames are sent.
The USE_RTS flag in iwm's LQ command enables RTS unconditionally, so only
set it while the AP is enforcing protection. The flag will be kept up-to-date

It looks like iwm firmware does not like a MAC context which does not

The driver currently adds such a context when initializing the hardware
for the first time after boot (with the BSSID set to all zeros, I also tried
a broadcast address and that doesn't work either).

This makes ifconfig display baudrates defined in ifmedia.h tables.
Before (prints media subtype):
$ ifconfig iwn0 | grep media:
media: IEEE802.11 autoselect (OFDM6 mode 11a)
$ ifconfig em0 | grep media:
media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause)
After
'instance' is the name of an ifconfig subcommand related to ifmedia
so the name of the setinstance() function is slightly confusing.

ifconfig scan displays RSSI (received signal strength indicator) values.
If the driver sets ic->ic_max_rssi the value is displayed as a percentage
of ic_max_rssi. Otherwise ifconfig displays the value as dBm.
The problem in the dBm case is that many drivers end up reporting a positive
value. The

Can you pin-point the iwm commit which changed this?

If the stack demands protection by setting the USEPROT flag then set
the corresponding bit in the Tx command regardless of frame length.

Your patch can't be applied with patch(1) because directory
components are missing on the Index: lines even though modified
files are spread across several
The wireless stack usually runs its scanning loop once per frequency band.
It begins with 5GHz so that APs on this band are preferred. Within a band,
an AP with the best RSSI (receive signal strength indicator) is chosen,
after matching all other desired parameters such as the ESSID etc.

Thank you for working on this, James.

Same rts threshold fix as for rtwn(4).

The rtwn(4) driver ignores the rts threshold value set by the stack.
This fixes it:

When I run iwn in monitor mode it flashes its LED like it
was trying to give me epileptic seizures.
With this diff, it's much less irritating.
ok?

Currently, if running in 11n mode, iwm always enables RTS/CTS to protect
frames it is sending.
To recap what the various HT protection modes are:
/*
* HT protection modes (see 802.11-2012 8.4.2.59)
*/
enum ieee80211_htprot {
IEEE80211_HTPROT_NONE = 0, /* only 20/40MHz HT STAs
Beacon filter settings in iwm(4) prevent the device from passing
beacons to net80211 while associated to an AP. The implication is
that net80211 does not see HT protection updates, so it never tells
the driver to update HT protection settings.
This can cause interference problems.
I believe this
I'm not sure if this change has any real effect, but as long as we don't
support 11n TX aggregation it's probably better to set the firmware's
aggregation limit to 1 frame (which means 'no aggregation').
