I've been having some fun with #FreeBSD again, and setup Jails to run in separate FIB's - https://fy.blackhats.net.au/blog/2025-12-02-freebsd-jail-fibs/
FreeBSD Jails in Isolated FIB (Routing Table)

@firstyear you could try turning off tso as well if you did want to go back to the other solution
@xssfox Yeah I saw that as another option too. I did try tso disabling and it didnt impact my setups throughput, only lro did.
@firstyear i hope you have more fun than i did with #leap16 。・゚・( ノД`)・゚・。
