SUMMARY: High rate of input errors on GE interface

My original message is at the bottom.  I've got no
answers from the mailing list, and only when I opened
service case with SUN Support I've got a solution:

they recomended to enable recieve and transmit pause:

ndd -set /dev/ge adv_pauseRX 1
ndd -set /dev/ge adv_pauseTX 1
 
(it looks like the second setting disabled by default)

Now I can go as fast as 75-80 Mbyte/s without any
errors.

regards,
Vladimir.
