I'm using Linux 2.6.6 with the Motorola Computer Group patch for the MVME6100 available at
https://mcg.motorola.com/cfm/templates/swDetails.cfm?PageID=704&Software ID=6&ProductID=202 and compiling with GCC from ELDK 3.1.1, although using the userspace module utils (e.g. insmod) from ELDK 4.0. The patch includes support for the Marvel gigabit ethernet part on the board (MV64360?) which works for non-jumbo ethernet frames, but doesn't receive (or even generate errors) if I send jumbo-ethernet frames. I haven't debugged this issue very long, but a cursory look through the driver hints that jumbo frame support should be on (the port config serial register PCSR has what I imagine to be okay bits). I'm ifconfiging the 2nd ethernet device with the command ifconfig eth1 mtu 9000 192.168.1.1 I'm wondering if anyone else using an MVME6100 has gotten jumbo frame support to work? Also, at what point did the Linux 2.6 kernel embedded PPC support start working with GCC 4.x (e.g. GCC in ELDK 4.0). I'm getting compiler errors when I use GCC 4.x with this version of the kernel. Tim
