Hi List,


because i've been asked, yes, the ixl3.15 interface is also UP (even my output in the last mail showed different, result of my desperate tries to make it work.

One thing I didn't mention, this is an onboard ixl on a Intel S2600STB Board, is has this wired config, were the first two interfaces are 10g base-t and the other two are sfp+ ports. While looking around further I noticed that only one of the sfp+ ports shows information on the sfp+ module correctly (both modules are genuine intel and have been cycled):


# ifconfig -v ixl2
ixl2: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9184

does not show the correct information (100G AOC, i'd wish ;) even thou it has the same kind of sfp+ as ixl3 here:

        lane 1: RX power: 0.57 mW (-2.41 dBm) TX bias: 8.20 mA

this made me thinking; is this 'wired' base-t and sfp+ configuration properly supported by the driver?

Any ideas from the list?


thanks & best

Hi List,


just recently I discovered a problem with the ixl(4) driver. Hopefully someone here can help me. my setup is as follows:


Network ----- ixl3 interface ----- ixl3.15 vlan interface ----- bridge0 ----- vnet0.1 to jail


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.
