This patch reworks the steps involved in roaming to a new access

This tid variable is used as an array index and must thus be smaller
than MAX_TID_COUNT (which is 8).
The variable will be set to 8 if the AP wants us to use TID 8 for Rx agg,
which I've never seen happen in practice, though it is possible.
Our driver uses this value as an index into an array of
The iwx Tx ring array is one entry too short due to an off-by-one error.
Fortunately, this bug is harmless. The last Tx agg queue is never used

And iterations over the txq array use nitems() to find the upper bound.

The last_rx timestamp which controls timeout of an Rx block ack
session is not updated when a frame is received.
This can result in the session timing out too early.
Not a huge deal because the AP will simply request a new session when
it has more data to send. And many APs do not even enable

then I will commit these changes to CVS incrementally. Thanks!
For those testing my iwx Tx agg patch:

This AP seems to use TKIP for the groupcipher and the iwx
setkey task doesn't handle this case properly.
Can you try this?

Some wifi drivers defer installation of keys into a process context.
There was a noticable race in the past which was fixed thanks to krw@
where link state was set to UP before key installation had completed in
hardware. This race could result in dhclient failing to get a lease.

Here is a rebase

tcpdump -e -v -y IEEE802_11_RADIO currently prints sequence number
and fragment number as a combined decimal value.
This patch makes tcpdump display these values separately which is a lot
easier to follow along as packets scroll by.
ok?

According to zxystd from OpenIntelWireless, the following change fixed
fatal firmware errors seen during HT protection updates for them.
I have not seen the issue myself, but I don't think this change can hurt.
If it fixes firmware errors in an edge case, all the better.
This essentially aligns
The mac context task gets triggered by changing parameters in beacons
received from our AP while ic_state indicates that we are in RUN state.
This can happen during regular operation and while a background scan
is in progress.
When a background scan has found a new AP, we trigger a RUN -> AUTH
This patch attempts to implement Tx aggregation support for iwx(4).
It is not yet ready to be committed because of outstanding problems:
- Under load the firmware throws a fatal firmware error every few minutes.
- Starting a background scan under load can cause firmware errors and
might error
I have found the reason for stuck connections over iwm/iwx
which people have been reporting against -current.
My commit which added support for Rx aggregation offload to these
drivers introduced a node leak. In other words, the reference counter
of ic_bss is incremented with every received frame,

Not everyone wants to read diffs in a browser.
Sending your diff inline will work better, like this:

Steven observed a panic ("iwm0: mac clock not ready") while testing
the iwm firmware update patch on a 9560 device.
I've also seen this happen one time, at some point during development.
In hindsight it is a bad idea to look at hardware register state here.
The point of iwm_nic_assert_locked() is
This patch allows iwm(4) to use new firmware images which are part
of the iwm-20210512 firmware package, available via fw_update (you
need to run fw_update *before* booting with this patch).
The new firmware images were published right after the fragattacks
embargo period ended. An advisory was
kettenis@ noticed that an athn(4) node cache can contain bogus clients
with MAC addreses that look like bit-flipped versions of MAC addresses
of legitimate clients.
I think this is due to my recent fix to allow block ack requests to
pass through athn(4).
The driver calls ieee80211_find_rxnode()
101 - 200 of 1452 matches
