Hi,
The axen(4) ( http://man.openbsd.org/axen.4 ) driver occasionally prints
a "checksum err (pkt#N)" warning message to the console/dmesg. The rate
I'm observing currently is about three per week, and what I see is that
it has no negative impact on the adapter's operation (i.e. what I see is
that it's a warning and not an error).
Observed on AMD64 6.0 and from the sourcecode the behavior appears to me
to be unmodified in 6.1 .
It's produced by a printf in dev/usb/if_axen.c (
https://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/usb/if_axen.c?rev=1.24&content-type=text/x-cvsweb-markup
).
Right now, luckily this printf line is the only match when grepping for
"checksum err (pkt" in the kernel sources, so it's easy to resolve the
cause and see that it's only a debug warning.
I would suggest to prefix it with "axen: " or alike, to decrease any
risk for user freak-out over it -or, maybe even more relevant would be
to disable it altogether - I guess the other NIC drivers simply silently
ignore any broken-checksum frames they receive?
Thanks,
Tinker
