[SI-LIST] Buffering 125MHz GMII signals

Hello All,
    I am using one Intel GIGMAC on our board and trying to interface the
GMII signals from MAC to other GMII device on daughter card.
 
When we simulated the GMII signal, we found that driver is not capable
of driving 10 inches of PCB Traces.
 
In this situation, is it a good idea to buffer the GMII signals(along
with the clock)? Have anybody tried buffering the 125MHz GMII signals in
Past?
 
If yes, can you pl suggest the buffers used at this high frequency?
 
I think this buffer should also have Very low pin to pin skew (to meet
the timing margins) and very fast driving capability.
 
Does anybody have any suggestions what other care should be taken in
choosing this buffer?
 
Any kind of suggestions will be a great help...
 
Thanks in Advance...
 
Rgds,
Samir
