ARP standard. I think it is RFC 826:
An Ethernet Address Resolution Protocol

The correct standard in this case is RFC1122 and it actually
offers two options for this: the so called strong end host model and the
weak end host model. Linux can be configured to be both. Default
is the later.

Please quote the section where it says that routing implementations
MUST round-robin over a group of interfaces with same subnet.

By use of a bridge interface, yeah. Are there other ways to get the
strong end host model?
