Haha this is awesome and insane. Are we really gonna go from 20 Mbps to 850
Mbps+ so quickly? I still need to get used to 130 Mbps!
Well single stream TCP is not quite there as I mentioned:

But yes, that's likely where we'll be for the next months with the
changes from the last three months and last three++ years.
It's slowly coming togther...
And don't forget the thanks go to the FreeBSD Foundation, the bug
reports to me ;)
Lots of joy and a blessed weekend,

Hi,
I had a bit of fun tonight after all and figured out what prevented me
from enabling VHT80P80 and VHT160 since January for testing. Patches
to come to review tomorrow (well that is today here). Turns out I cannot
test VHT80P80 currently.
This is likely the first VHT/160 assoc on FreeBSD so I thought I'd send
the email.
And I ran the simple silly iperf3 test.
Not much more than VHT80 but I am also sure I am starting to hit other
limits in this test setup. It goes from the AX210 in a bhyve instance
to AP to a small 4 port switch and back into em0 on the same laptop
just the base system running the iperf3 server.
Down there is UDP TX from the wifi set to 960Mbit/s target rate.
Don't expect that with single stream TCP. Yet another thing to debug ;)
Keep in mind we are still copying the full frame incl. data from
skb to mbuf or vice versa depending on direction and other fun bits
to optimize one day. I guess I'll try to find an AP supporting 11BE
and SFP+ for 10G DAC or fiber for christmas this year... until then it'll
be other things to get us stable first.
Try it our yourself please -- even with VHT80!
Lots of joy
