I'd like to report additional nits with i217: While trying to track down strange symptoms (IPSec transport mode seems broken, virtualbox bridge might possibly also be broken), I saw that disabling some offload features doesn't work. ifconfig(8) doesn't report a failure, but I can't disable VLAN_HWCSUM and disablying rxcsum6 enables rxcsum4, while disabling rxcsum re-enables rxcsum6. Is it possible at all that iflib affects IPsec transport mode? Thanks, -harry
