Merged the fix into 12.0-U6.

I've bought one of those cards and was able to reproduce the issue from the first attempt. It seems to be a bug in the bnxt(4) driver. It reports IFCAP_WOL_MAGIC capability enabled, but not supported. I haven't looked how it works for `ifconfig` command, but it causes error when middleware tries to do change any other capabilities directly via IOCTL. I am working on a fix.

Hi Alexander,
still an issue in upstream, it seems:

Kind regards,

This is what we end up with in 11.3 with just the box checked and no explicit removal of capabilities - but explicit adding of "promisc":
bnxt0: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 1500 description: Trunk options=8120b8<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWFILTER> ether 00:25:90:5f:99:ac hwaddr 00:25:90:5f:99:ac nd6 options=9<PERFORMNUD,IFDISABLED> media: Ethernet autoselect (1000baseT <full-duplex,rxpause,txpause>) status: activeSo it looks to me like these are applied correctly:
-rxcsum -rxcsum6 -txcsum -txcsum6 -tso -lrowhile the VLAN specific ones aren't.

The error messages you see in UI are caused by IOCTL error returned by the driver/kernel, that is why I am thinking about correlation with the VLAN issue. So if you haven't seen them before, it may mean either driver regression or some middleware change. Was it working in 11.3-U5, like really removing the capabilities, or just ignored the error?
Hi folks,
the upgrade to TN 12.0-U2 went really smooth and all of the minor annoyances seem to have been fixed for us - besides two problems with bnxt(4) interfaces. This report is about one of them, I will have to find a way to create a proper JIRA issue for the second without affecting production. I have only two AMD Epyc based systems with that network interface and I need them both
Long story short: checking the "Disable Hardware Offloading" option and clicking "Apply" leads to a Python exception. Technically the system works well if I recreate the functionality by putting this into the "Options" field:
-rxcsum -rxcsum6 -txcsum -txcsum6 -tso -lro -vlanhwtag -vlanhwtso -vlanhwfilter -vlanhwcsum
It would be nice to be able to use the UI properly, though.
Kind regards,
Patrick
P.S. If Alexander is working on this - the second problem is still VLANs not working at all without explicitly configuring "promisc" for the bnxt(4) interface in question. But I will create a separate issue for that one.
