[Bug 276760] vtnet driver incorrectly calculates checksums

So you are basically saying, the it doesn't matter if you use pf or not. That
is great.
Let us focus on the vtnet scenario (not the jail) and on the receive side.
There is a substantial difference triggered by the offload. I did the same test
locally and got less bandwidth than you, about 260Mbps. But it was consistent
on multiple runs and enabling or disabling the offload did not show an impact.
The system was not CPU limited.
So could you measure that a couple of times and see if disabling offload
roughly doubles the receive rate? Could you also prove the output of sysctl
dev.vtnet.0 and sysctl hw.vtnet?
