So, seems to make things better. =-)
I tried it again this morning, on the off-chance that the stars didn't
align yesterday. Same deal:
sh-3.2# sysctl net.link.generic.system.hwcksum_tx=0
net.link.generic.system.hwcksum_tx: 1 -> 0
sh-3.2# sysctl net.link.generic.system.hwcksum_rx=0
net.link.generic.system.hwcksum_rx: 1 -> 0
sh-3.2# ifconfig en0 -rxcsum
