We turned off TCP and UDP checksum verification a few years ago:

(based on the date, this probably first showed up in version 1.2)

But this reminds me: sometimes I see IP checksum offloading causing 
problems now, which we do still check by default.  We should probably 
disable this verification by default as well.
