upfront: rtw88/rtw89 and older iwlwifi chipsets all need more work which<br>
will continue. rtw88/rtw89 need LinuxKPI and net80211 changes, modern<br>
iwlwifi chipsets will need a net80211 change for a clean solution which<br>

driver changes due to GPL-only code.<br>
<br>
If you have an iwlwifi AX2xx or BExxx and you have successfully tested<br>
HW_CYRPTO (see the other email thread here on wireless) then you have a<br>
chance to test a first cut of HT20/40 and VHT20/40/80 (no 160 yet)<br>
support by adding the following two tunables next to your hw_crypto one<br>
in loader.conf:<br>

compat.linuxkpi.iwlwifi_11n_disable=0<br>
compat.linuxkpi.iwlwifi_disable_11ac=0<br>
<br>
If you try this with any other (older) iwlwifi chipset (anything with<br>
just numbers 3xxx, 7xxx, 8xxx, 9xxx etc.), with rtw88 or rtw89 it will<br>
fail and I'll not provide support at this time unless you want to help<br>
to make it work. Otherwise you'll have to wait a few days/weeks<br>
longer -- sorry.<br>
<br>
Also if you try this without the hw_crypto tunable on, it'll fail badly,<br>
so please test that (independently) *first* if you haven't as that will<br>
be my first question.<br>
<br>
I am sure there'll be plenty of rough edges to fix for me... but I<br>
wanted to get the code out at this point.<br>
<br>
The last bits of the code have been in stable/14 since yesterday [1] and<br>
main since [2] (beware that main has more wireless changes I haven't<br>
rebased to yet for extra testing but they should not interfere).<br>
<br>
Once we have sufficient confidence that things work well enough I will<br>
