- Subject: Ethernet MTU
Has anyone used jumbo packets (MTU of ~9000) with the RTEMS networking
stack? I have a working gigabit network stack up on the PPC405EXr, but
I'm not seeing more than 17Mbytes a second throughput. I understand
that using a larger MTU would make quite a difference, but its not
clear to me how to reconfigure the interface to do it. I can get the
necessary information out of the PHY without any trouble, the question
is what to do when it says it has made a gigabit connection...
Thanks for any comments,
Wi not trei a holiday in Sweden this yer?
