For tcprecvoffload and ix(4) it's not possible to enable/disable it per

For tcpsendoffload its possible, but I won't do that till its necessary.
Why would you want to differentiate the address families here?
I was mostly just curious as I see FreeBSD seems to support this.
That made we wonder if there is hardware that only supports offloading
for IPv4.
I know that em driver only supports TSO4 on FreeBSD.
It's not enabled by default but users can enable it.
See the following code for detail.
