    SubjectRe: jme driver loses connection after resuming from suspend
    From
    Hello Guo-Fu Tseng, not good news, the patch is not working.

    But i've noticed one interesting behavior.

    I've done 2 tests, on the first i've suspended, resumed and after
    resume done a tcpdump. Only after the tcpdump, the network starts to
    work.
    ethtool-before
    ethtool-before-d
    ethtool-after
    ethtool-after-d
    ethtool-after-tcpdump
    ethtool-after-tcpdump-d
    on the second test, i've done the tcpdump befor suspending, and after
    the resume the connection works.
    ethtool-before-2
    ethtool-before-2-d
    ethtool-before-2-tcpdump
    ethtool-before-2-tcpdump-d
    ethtool-after-2-tcpdump
    ethtool-after-2-tcpdump-d

    I've attached the ethtool logs, and they are listed in the order of the steps.

    i hope we can solve this mistery.
