It's always the sender doing the load-balancing, so that should be
possible by just using two different algos on each side of the link.
Alternatively, e.g. if you have more than just two switches, you might
get good results with "src-dst-mac".

I'm pretty sure none of the Catalyst switches can recognise PPPoE and
extract L3 information from the packets, so there's just the MAC
addresses.
