 I wonder if this is a manifestation of the problem I saw about a year
 I installed a QFE card in a SPARCstation 5, which I was using as my NAT
 router with "pf" (netbsd-7).  The first thing I noticed was that FTP
 connections would fail being passed to 'ftp_proxy' if tcp4csum-tx were
 set on the internal interface.  Later, I experienced bizarre failures
 visiting the web site of a motel chain attempting to check availability
 of rooms.  Disabling all the hardware assists didn't fix the problem.
 I didn't try forcing the media as 'automatic' seemed to Just Work(tm).
 When I replaced the SS5/QFE-based router with a Soekris net4501 using
 the exact same "pf" rules (modulo interface names), the problems went
 Prior to the QFE card, I was using the 10Mb/s qec(4) card in the same
 SS5 and it worked just fine.
 I had also used multiple discrete HME cards in NAT routers built out of
 SPARCstation 5s with quite some success, but that was prior to netbsd-7.
 If I can round up enough of them, I could try that again.
