[RFC] interface for outgoing packet

Hi All,

How reasonably I can assume that,

on whatever interface, I received the last packet
for a particular Socket Connection, the same interface will be
used to SEND the next packet for same socket connection?

I am collecting the logs on one of my test machines.
And it shows, I can assume all the time that "interface" which received packet
for some socket connection, the same will be used to send packet for
that connection

But, I am not sure if I am missing some scenarios
or setup (for e.g., bonding) where it can be wrong ?

It would be more help if some one can shed some light.
