There appear to be two issues in the referenced bug: (1) VELOCITY_MIN_MTU is hardcoded at 1500 bytes in via-velocity.h, and (2) An earlier version of the via-velocity driver couldn't handle on-the-fly MTU changes. Number (2) was resolved with a patch. Number (1) was not. I intend to submit a patch to kernel.org, but first, can someone confirm that the proper way to alter MTU size is: ifconfig <interface> mtu <size> service network restart I can't get it to work unless I bounce the network service after making the MTU change. I just need to know if that's normal. Thanks, Jay -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
