Title:
OVN provider network type vlan packets cannot go outside the bond on
Intel E810-XXV card

I found the compute from which the outside traffic is going out
and I see ARP requests with no response

For the test you may ping .254 indifenetely
The error count grows on tx packets on bond1 and the card ens2f0 (which
happens to push the traffic)
ubuntu@compute-09:~$ sudo ethtool -S ens2f0|grep error
tx_errors: 12
tx_errors.nic: 0
rx_length_errors.nic: 0
rx_crc_errors.nic: 0
ubuntu@compute-09:~$ ifconfig ens2f0
ens2f0: flags=6211<UP,BROADCAST,RUNNING,SLAVE,MULTICAST> mtu 9000
ether b4:83:51:00:83:d1 txqueuelen 1000 (Ethernet)

RX errors 0 dropped 0 overruns 0 frame 0
TX packets 52163 bytes 18393142 (18.3 MB)
TX errors 12 dropped 0 overruns 0 carrier 0 collisions 0
If I create vlan interface directly on bond1 I can ping the gateway with no
problem
so that creates opportunity for
WORKAROUND 1: set the network to flat and push traffic on vlan interfaces on
computes as for physnet device
Another thing I tried was to install the HWE kernel
ubuntu@compute-09:~$ uname -a
Linux compute-09 5.15.0-60-generic #66~20.04.1-Ubuntu SMP Wed Jan 25 09:41:30
UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Fortunately traffic was still going out from compute-09 after reboot,
that fixed the issue
so we have WORKAROUND 2
ubuntu@ubuntu-provider2:~$ ping 10.99.0.254

^C
ubuntu@infra-1:~$ ping 10.99.0.213
PING 10.99.0.213 (10.99.0.213) 56(84) bytes of data.

64 bytes from 10.99.0.213: icmp_seq=6 ttl=62 time=1.05 ms
Now I can ping both ways
However I am afraid that we may encounter same issue like for Jammy for the
cards when booting, as it happens randomly for the kernel with the same number
5.15.0-60
