<p>Hi List,
<br>
<br>
<br>
just recently I discovered a problem with the ixl(4) driver.
Hopefully someone here
can help me. my setup is as follows:
<br>
<br>
<br>
Network ----- ixl3 interface ----- ixl3.15 vlan interface -----
bridge0 ----- vnet0.1 to jail
<br>
<br>
<br>
the problem now is that the jail can send data out (arp requests),
i do see the responses on the ixl3 interface of the host, but they
never make their way up to the ixl3.15 vlan interface (even though
they are tagged correctly). To rule out that my config or the
network is the cruel pit i did test the same setup with a cheap
usb-ethernet adapter and there everything works as expected. I'm
on FreeBSD 13.2-RELEASE-p8 and I did test both, the in kernel
driver and the driver from ports intel-ixl-kmod-1.13.4_1.
