Bug Description
Detailed bug description:
Some ethernet drivers have offloading mode defaults that need tweaking in order for VLAN traffic to pass as expected. For example:
driver: amx_xgbe (aarch64 hardware);
offloading modes (only relevant):
rx-vlan-filter (defaults to ON, discarding VLAN tags, we want that to be OFF).
Expected results:
Offloading modes for target NICs are only applied during provisioning/
Actual result:
Offloading modes ain't applied during network-check.
Workaround:
* Skip running netcheck, or expect the VLAN traffic to NOT pass; since offloading modes are not applied during that test;
* Apply offloading modes by hand for bootstrapped nodes (e.g. from Fuel Master, issue `ssh root@node-X ethtool ethN -K rx-vlan-filter off` (for each inteface affected on each node).
Impact:
By running the network check after properly configuring offloading modes, one may think the network settings are wrong when the network check fails, although that is a false report, as deploy would work just fine.
