>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
