[c-nsp] 3750 etherchannel only using 1 port

The src-dst-ip works on any switch at any level.  I use it on 2960 
switches 3550, 3750, 6509, etc.  It works on everything but my 3750 and 
i'm not even doing cross stack etherchannel on the 3750 so I don't know 
what is up with it.   I can't play around with it too much since It's in 
operation and I wasn't expecting it to break in 12.2.44SE1 :/

See what I mean??  It's router to router so MAC won't work and there are 
thousands and thousands of ip addresses going through this so the 
src-dst-ip should work no problem, but it doesn't. :/

I don't get it.. I've tried changing it to dst-ip, src-ip, even mac and 
still no luck.
I've never seen etherchannel not work before like this.  A 2960 switch 
plugged into the same device works with src-dst-ip no problem.
