Error description
4-Port Gigabit Ethernet PCI-Express Adapter (e4143a16e4143009) configured with checksum_offload and/or large_send will send packets with bad tcp checksum. This is seen only when sending vlan packets, thus coming from a vlan adpater or a VIO client using SEA with vlan.
Local fix
disable both checksum_offload & large_send on the physical adapter.
Problem summary
Setup vlan and enable checksum offload,there will be an initial delay when using the vlan interface.
Problem conclusion
Update the tx_bd_nbytes in case of vlan tagged frames.
Temporary fix
