Or perhaps that is a trigger but the problem is elsewhere. bentley@ saw similar wg(4) problems on a machine with just em(4): em0 at pci0 dev 31 function 6 "Intel I219-V" rev 0x21: msi, address 94:c6:91:a3:6d:8a Now, if I looked at the right files, only ix(4) vm(4) vio(4) have LRO - em(4) does not. We do support TSO on some em(4). Though, while I am not certain, I don't think we do on I219-V... Anthony, do you still have that machine available? Can you do an "ifconfig em hwfeatures" please so we can be sure? My best guess from the information I have (I don't think it's possible to map from a dmesg attach line to a mac_type without more information - the pci id isn't printed) is that it's an em_pch_spt which doesn't do TSO...
