[Sunhelp] tweaking TCP stack parameters under Solaris?

[Bill Bradford]

Anybody know if its possible to tweak/change the values of the
following settings in Solaris/SPARC?  I figure its an /etc/system
setting but I have no idea what to specify.:

MTU (maximum transmission unit)
RWIN (TCP Receive Window)
MSS (Maximum Segment Size)

Thanks.

Bill
