It is doubtful that you can do *specificly* this.

What you really want to do is called 'bonding', where you bond two (or
more) NICs into a single logical NIC. Linux does support this. You
need to be sure your EtherNet switch supports it as well. Oh, it really
only makes sense if both machines (server AND client) are doing this.

You will get the same bandwidth effect as you want, since if you really
pull/push data at a rate high enough, the kernel will load share across
the two (or more) NICs, although you won't have any one NIC *dedicated*
to reads or writes (just like on a SMP system you won't have any one
processor dedicated to any specific processing).
