According to NetBSD's source, it seems HME is "SIMPLEX" if used
in full-duplex mode. But I can't sure it affects both 10Mbps and
100Mbps mode.
How about attached patch(not tested, borrowed from NetBSD)?

PS: Due to real life thing I have little time to test/experiment
    /commit this one. It would be great if any committers can hanle
    this.
