The driver/hardware for rtl8139 seems to be limited at 4096: bryan@desktop:/mnt/store/git/linux-git/drivers/net/ethernet/realtek$ grep 4096 * 8139cp.c:#define CP_MAX_MTU 4096 8139cp.c: RxErrLong = (1 << 21), /* Rx error, packet > 4096 bytes */
I wonder if ifupdown can handle this better and report that the MTU is to high.. maybe even fallback to maximum and note it in the logs? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1430993 Title: MTU can't be higher than 4096 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1430993/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
