Don't try to listen on UDP sockets.
Comment out nfrac as it's unused.
enable IPSEC
Don't grab libstdc++-v3/config.h it's not used.
Remove unused files.
\%s is not an escape sequence, and we want %s
hashinit: replace loop with a formula.
Work around broken GTT size detection in agp_i810 code.

This will do until I work out the twisty maze of registers, all
different, to reliably determine the size of the GTT (and hence the
GPU's virtual address space) separately from the size of the AGP
aperture.
Make IGMP and multicast group management code MP-safe.  Use a read-write
lock to protect the hash table of multicast address records; also, make it
private and eliminate some macros.  In the long term, the lookup path ought
to be optimised.
mention new ipsec sysctls.
Introduce 2 new variables: ipsec_enabled and ipsec_used.
Ipsec enabled is controlled by sysctl and determines if is allowed.
ipsec_used is set automatically based on ipsec being enabled, and
rules existing.
Explain ipsec.enabled better.
netstat(1) and ifmcstat(8): ifnet was renamed to ifnet_list, PR/48850.
No need for libkvm here.
Include cdefs.h earlier for NetBSD.
Use __CTASSERT() in the header.
tcp_signature_getsav: handle !ipsec_used case and fix the build (hi christos!).
Remove !NetBSD code.
Kill __P. Use static.
Add Intel 3200 Host and PCIe.
