Title:
misleading kernel warning skb_warn_bad_offload during checksum
calculation
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Xenial:
Fix Released
Status in linux source package in Zesty:

Bug description:
Even when the packet says checksum calculation is unnecessary the
kernel will still check the checksum and display a warning that the
checksum is bad.
This has been fixed upstream in Kernel 4.11 by commit id:
