net.link.ether.inet.useloopback

[Adam Clark]

Heya,
  I would like to make packets destined for an IP address bound to a
network card
Get dropped onto the wire so I can do some QoS on it.  I found the the
following sysctl variable
But am unsure about what it does.  I cannot find any documentation on
it.

net.link.ether.inet.useloopback

It is currently set to 1, so enabled.  I had a comment from someone that
the kernel uses the loopback interface to
Pass packets destined for itself (not nessasarly just the 127.0.0.0/8
network), maybe this will stop the kernel from performing this action
and drop it onto the wire the ip address is bound to.


Cheers
