ethtool/tc for NetBSD?

[Darren Reed <darrenr%netbsd.org@localhost>]

Is there a NetBSD equivalent to ethtool(8) on Linux?

http://linux.die.net/man/8/ethtool

As an example, to drop ICMP packets:

ethtool --config-ntuple eth4 flow-type ip4 proto 1 action -1

... and the NIC drops them all for you, not an interrupt in sight in 
response to ICMP (but there's also no logs...)

The other interesting and obscure Linux networking command is "tc".
