ThunderX: TX failure unless checksum offload disabled
Status in linux package in Ubuntu:
Status in linux source package in Artful:
Most attempts to use IPv6 on the ThunderX NIC will fail.
Attempt an IPv6 TCP connection:

The connection will time out.
The fix is upstream, and is limited to the ThunderX nicvf driver.
Disable TX checksum offload:
$ ethtool -K eth0 tx off
