Summary : Slow FPT on ULTRA 200 E

First of all thanks to all who replied. Most suggestions were to install
Solaris 2.6. When I called SUN they also told me that the minimum
requirement for this system would be Solaris 2.5.1. Following all of these
suggestions I installed Solaris 2.6 and downloaded all patches. The result
was interesting my output rate increased to 1 Mbps but sending speed was
only 10 Kbps.

After checking out driver configuration parameters I realised that both
10fdx_cap and 10hdx_cap are set to 1, so I set it manually to duplex and
disabled auto_negotiation mode. I also found that similar question
appeared earlier and that summary was helpful. At the end it increased the
sending rate to 600kbps. There is still problem with the delay of certain
packets but that is another story :)
