[stable-9]

[Li, Qing]

The route selection is based on a hash function of source-ip and destination-ip when 
RADIX_MPATH is enabled. You do not need to perform specific actions, other than perhaps
setting varying weights on each entry as an option. So depends on the traffic destination 
the chosen route may always be the same one.

Trying to use two interfaces connected to the same network with the same
default router.  The two interfaces have two different IPs on the
same /28 and point at the same default router of .1.  I have
successfully configured the machine such that data is coming *in* on
both interfaces, but the output is only going out the first interface.

I've compiled with RADIX_MPATH enabled, and I'm setting the default
route ... but, I'm pretty ignorant what to do next.  Chances are, I'm
just being stupid here and I need to get more sleep.

-bash-4.2$ netstat -r
Routing tables

Internet:
Destination        Gateway            Flags    Refs      Use  Netif
Expire
default            <redacted>         UGS         0 33320033   igb0
XXX.XXX.XXX.0/25    link#1             U           0        0   igb0 =>
XXX.XXX.XXX.0/25    link#2             U           0        0   igb1


What am I missing here?

Sean
