By the way If I use vlan on top of nic, it seems OK, so bonding is the
suspect ?
$ ip link add link eth3 eth3.103 type vlan id 103
$ ifconfig eth3.103 up
$ ethtool -k eth3.103
Offload parameters for eth3.103:
rx-checksumming: on
tx-checksumming: on
scatter-gather: on
tcp-segmentation-offload: on
udp-fragmentation-offload: off
generic-segmentation-offload: on
generic-receive-offload: on
large-receive-offload: off
rx-vlan-offload: on
tx-vlan-offload: on
ntuple-filters: off
receive-hashing: off
