Ok, I looked (minimally), and I _think_ Linux is generally allowing the higher value to be set on the interface, and depending on path MTU discovery or fragmentation to take care of it if for any particular situation (lower connection MTU or multicast/broadcast requiring UD rather than CM) that's misled e.g. a datagram based application into sending large packets. (my very quick take on the first hit on google for "ipoib-cm" linux mtu) -- This message posted from opensolaris.org _______________________________________________ opensolaris-arc mailing list opensolaris-arc@opensolaris.org
