    I tried this one and seems to work corectly :) Jumbograms were used, data stream was smooth,
    I haven't seen any error messages in system log.
    In rough tests I had a little bit better speeds than with this one:
    http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/if_sk.c.diff?r1=1.51&r2=1.52
    But I only tried netperf with maximal message send size on similar boxes, if you'd like some other tests,
    let me know the details.

    By the way - do you know if sk(4) driver supports device polling (man 4 polling)? I know there were some plans
    to make it work, but I couldn't found any up2date information.
