X-Mailer: VM 6.75 under 20.4 "Emerald" XEmacs Lucid Sender: owner-freebsd-stable@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I have been told that the MTU of 1500 bytes is hardcoded into the 10Mb ethernet standard. Fine. But a number of devices seem to allow for MTUs > 1500 on 100Mb ethernet... and several people have told me that the standard allows for packets bigger than 1500 bytes. Specifically, this seems to be the case to allow VLAN trunking with larger than 1496 MTUs which is the cause of much frustration among some of my DSL users. However, it appears impossible to set an MTU larger than 1500 on a FreeBSD ethernet interface. Is this hard to change?
