>Description:
The sk(4) man page states "Hardware TCP/IP checksum offloading for
IPv4 is supported." under the description section, then under bugs it
states "Support for checksum offload is unimplemented." I infer the
latter is correct, as it was added in a later revision?

Since the Hackathon is approaching, I thought I'd take a look at old
PRs I'd filed that were still open. In this case, it appears from
code inspection that the answer is that IPv4 hardware checksum off-
loading is not supported, given there's only one reference in the
most current version of if_sk.c that appears relevant. On line 1397
I see "ifp->if_capabilities = 0;" and that's it... And from looking
at the revision history for the man page, it was imported with the
"is supported" statement, and someone added "is not supported" under
the bugs section later.
Another question: the man page still says "This driver is
experimental" under bugs. There have been some revisions made to
the driver in the intervening years, is it still considered such?

Drivers are experimental until someone decides they work well enough
to not be experimental any more. The driver's in GENERIC and not
commented out, for which "no longer experimental" is roughly the
criteria, so probably that statement should be removed.
I take it you have the hardware? Does the driver more or less work?

No, actually, I don't. At the time I read through the man page, and
noticed the conflicting statements, I was evaluating various Ethernet
cards' support status in NetBSD.

I keep getting reminders from the Gnats software that I need to
provide feedback, but I already have done so, could someone please
change the state of this PR?
Thanks,
Dave
