I tried this one and seems to work corectly :) Jumbograms were used, =
data stream was smooth,=20
I haven't seen any error messages in system log.=20
In rough tests I had a little bit better speeds than with this one:=20
http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/if_sk.c.diff?r1=3D1=
.51&r2=3D1.52
But I only tried netperf with maximal message send size on similar =
boxes, if you'd like some other tests,=20
let me know the details.=20

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.=20
