Hi, I am unable to build i40 driver version for kernel 4.9.337 with CONFIG_I40E_DISABLE_PACKET_SPLIT=1. Since it does not seem to be possible to report a bug in SourceForge project anymore, here is a description of the problem.
Building i40e driver version 2.22.20 for kernel 4.9.337 with
CONFIG_I40E_DISABLE_PACKET_SPLIT=1, build fails - see console output extract
below:

But there is another build error - see console output extract below:
