Something similar is needed for xdp and not necessarily tied to a
specific bond mode. Some time back I was using this as a prototype:

https://github.com/dsahern/linux/commit/2714abc1e629613e3485b7aa860fa3096e273cb2

It is incomplete, but shows the intent - exporting bond_egress_slave for
use by other code to take a bond device and return an egress leg.
