Jumbo frame support is required in the 'ixgb' driver which will improve network performance.
The ixgb driver requires to support hardware checksum offload. It can highly improve the network performance.
Two machine connected back to back with ixgb interface. Configured vlan interface on each machine'ixgb interface. But it cannot ping the other one through the vlan interface.
The following is the test log.
