Hi Navdeep,
I already got rid of the hw.cxgbe.num_vis line in loader.conf when I
rebooted this morning.
dev.t5nex.0.firmware_version: 1.15.37.0
I tried this exact firmware and was able to reproduce the problem. This
appears to be a firmware bug that has already been fixed in the 1.16.x
firmware available in 10-STABLE.
Regards,
Navdeep

I'll try to repeat the experiment with a T520-SO with the firmware that
you have on your card. Does the card behave this way if the extra VIs
are not created? Can you please try without hw.cxgbe.num_vis in
loader.conf?
Regards,
Navdeep

The card is a 'T520-SO Unified Wire Ethernet Controller'
I ran the following with dtrace running in a separate window
ifconfig cxl1 promisc up ( only see broadcast)
ifconfig cxl1 -promisc
ifconfig cxl1 promisc (now I see traffic)
dtrace output was
[root@goose2 /usr/home/joe]# dtrace -n 'fbt::t4_set_rxmode:entry

Hi Navdeep
running "ifconfig up" and then "ifconfig promisc" works. Running
"ifconfig
promisc" and then "ifconfig up" does not work. Running "ifconfig up
promisc"
together does work. Running "ifconfig promisc up" does not work.
What version of FreeBSD is this? I couldn't reproduce this on head
with
a T6 card. Can you please run this in parallel with your ifconfig
commands, note what dtrace logs in response to what command(s), and
send
the output to me?
# dtrace -n 'fbt::t4_set_rxmode:entry {trace(arg4)}'
The combination that does not work leaves the interface in a state
where it
reports it's self as being in promiscuous mode.
In my experiments the interface did function in promiscuous mode
whether
I did "ifconfig cc0 promisc up" or "ifconfig cc0 up promisc".

Navdeep
