What you're suggesting requires the following:
1) Support in the switch for load-balancing incoming packets to the
multiple interfaces on the host (each having the same IP address).
2) OS support for allowing same IP address to be present on multiple
interfaces.
Why go for the above costly solution when the same effect can simply be
achieved by connecting multiple interfaces with different IP addresses with the
vanilla OS ? Also as Julian remarked, many high-end servers already use the
configuration that I'm using. I'm not aware of any specs that conflict with
this configuration either.
