Bug in Broadcom bnxt driver in combination with VLANs
-
I think I'm running into the same issue. Brand new Dell server with BCM57416. Works fine with single VLAN assigned to the nic, as soon as I add a second VLAN, I get the "Attempt to re-allocate" error on screen and everything breaks. Haven't found a way around it yet.

You would need to recompile the driver with the patch and load it as a module. Non-trivial.
It's not included upstream yet even in main: https://github.com/freebsd/freebsd-src/tree/main/sys/dev/bnxtSteve

@stephenw10 said in Bug in Broadcom bnxt driver in combination with VLANs:

So, I assume you'd suggest going back to 2.6 for now?
-
Since it looks like that's in VLAN filtering in the driver you could try disabling VLAN hardware off loading on the NIC.

@stephenw10
Thank you for that suggestion. The idea was promising, but unfortunately not successful. I tried:ifconfig bnxt0 -vlanhwtag -vlanhwfilter -vlanhwtso ifconfig bnxt1 -vlanhwtag -vlanhwfilter -vlanhwtsoBut the errors remain :(
-
I'm also interested in a workaround, we plan to use the Broadcom BCM57416 with VLANs.
-
Mmm, worth trying but I did expect to see that on the FreeBSD bug report.
In he short term going back to 2.6 may be the only option.

@stephenw10
Can you point me where to look if I want to try and recompile this for myself?
I'm a beginner but I would like to try to get my NIC to work with more than 1 VLAN -
As far as I can see there is no validated patch for this yet: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=269133#c31

@stephenw10
A bummer, but can't be helped! I'll have to find other uses for the NIC in the meantime.
Thanks for the quick response! -
@tmoehle Did going back to 2.6 make the VLANs functional?
I tried it for a bit and didn't get anywhere (didn't get the re-allocate error but the interface didn't forward any traffic)
Going back to 2.6 permanently also seems cumbersome since I could not install packages from the package manager until I update to 2.7 again. -
You can install packages, just set the repo branch to 2.6 (deprecated).

I did a clean install for pfsense 2.6 and restored the old configuration backup. That went perfectly smooth. After that, as @stephenw10 already suggested, I went to System > Update and changed the desired branch to 2.6, so I could download packages again. -
@tmoehle
Encouraging to hear! I will give it a(nother) proper go then.
Silly me just read an old forum posts about the packages requiring an update, which I somehow can't find anymore so I probably didn't read something correct when I was looking for a place to download 2.6 -
@tmoehle Sorry for prying a lot, but do the VLANs on your NIC really work?
I installed 2.6 and the NIC works without VLANs.
When I create a VLAN and assign it to an interface, No traffic gets through (oddly enough the DHCP does work)
When I set a different network port (non bnxt) with the same VLAN to the same configured interface, it all works (albeit I have to reload firewall rules first).I am hoping that I am doing something wrong, since DHCP somehow still works on the VLAN with bnxt, but I don't see any issues with the gateway and the firewall rule permits the traffic.
-
@Delegator5042 My VLANs are working perfectly fine, yes. If your DHCP is working within those VLANs and pfsense is your only DHCP server, then chances are you overlook something.
-
This should now be fixed in the next 23.09 snapshots if anyone can test that.

@stephenw10 Will it only go into 23.09 or will there also be an update for CE?
-
It's fixed upstream in FreeBSD so it will be pulled into new CE builds.

@stephenw10 Hi. With pfsense version 2.7.0 im still facing this issue.
Will it get resolved in 2.7.2 or should i downgrade?
