The NetBSD version is known to work with the VMWare LANCE (it actually
also has the same workaround as lnc(4) for a bug in the emulation) so
I think the ported version also will. I haven't given that a try so
far however and only tested it with real PCI hardware as my main goal
is to get it into RELENG_6 as soon as possible in order to get it
into 6.1 (without replacing lnc(4) in the default config). If someone
could give it a try with VMWare so I don't need to get a copy and
probably a Windows installation that would be really great though.
My plan is to let le(4) replace lnc(4) in the mid term however.

Regarding getting it into RELENG_6 for inclusion in 6.1 what time
for the MFC would you prefer from the re@ point of view?
