My setup is a Java Workstation W1100z with the integrated bge0 going via crossover to my laptop (9000 MTU no problem) and a 32-bit Intel e1000g0 installed for WAN in the same W1100z w/ 1500 MTU. I've added the following to /etc/system : # Add support for jumbo frames for Broadcom NetXtreme 5703 bge NIC set bge:bge_jumbo_enable = 1 while the /kernel/drv/bge.conf has: # see http://www.opensolaris.org/jive/thread.jspa?messageID=48569 # default_mtu=9000; # default-mtu=9000; default_mtu=8000; As you can see above, I've commented out the MTU 9000 setting since they didn't work. Even with only the 9000 MTU settings in bge0.conf the following is still the result: # ifconfig bge0 mtu 9000 ifconfig: setifmtu: SIOCSLIFMTU: bge0: Invalid argument However, with the same 9000 MTU settings in bge.conf above that don't work, I can set an 8000 MTU with ifconfig without a problem. I've done many tests with reboots just to be sure between most of this and the result has been the same for me. An 8000 MTU is no sweat, but a 9000 MTU just hasn't happened. An 8000 MTU greatly helps my NFS over a 1500 MTU, but I still have more fragmented packets than I'd like, and what the hardware supports. -Wes W.
