ethtool/tc for NetBSD?

[Darren Reed]

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".

That's more a feature of the particular driver. I'm not
aware of any NetBSD driver that supports such features.
There is no API or userland command to control such a
feature. A driver would probably offer some sysctl variable
instead.

The tc command controls traffic shaping in the Linux kernel which
is somewhat an equivalent to NetBSD's altq.
