Hi, I'm currently testing jumbo frames on a Sunfire 4540 running with FreeBSD 8-Current (build on April 8th). While using the nfe driver I'm having some unexpected problems if i try to bring up the interface with MTU sizes greater than 1970 bytes. The error message (in dmesg) is: nfe2: initialization failed: no memory for rx buffers I tried to deactivate checksum offloading with -rxcsum -txcsum, but that didn't help either. If I change the mtu size on-the-fly without bringing the interface down first, no error is logged. But the interface just isn't working. Does anyone have any ideas how to get jumbo frames working?
