The log entry for the previous commit marked an item
relating to filling in [mca]time data for socket structures
as related to FIFOs. The change is actually related
to sockets.
of using the MGETHDR macro all the time. When an mbuf is reused as a
header, initialize csum_flags to zero as well, so the delayed_checksum
call woks properly.

This is almost certainly an alpha infrastructure bug, not a FICL
problem. It's probably the same thing that made FICL fail for no
apparent reason on the Alpha.
NETGRAPH is not present in GENERIC at the moment. Also, change some
settings to support USB installs:
- Add KBD_INSTALL_CDEV as an option to make /dev/kbd[01] actually work.
- Turn on keyboard probing in sc0. The syscons driver will now use a
flag documented in ukbd(4) but not in sc(4) that tells syscons to
actively search for a keyboard device if none is found. This allows
USB keyboards to just be plugged in and instantly start working.
- Require the atkbd0 driver to actually probe to see if a keyboard is
there. This allows USB keyboards to be seen by sc0 if an AT keyboard
isn't plugged into the computer. This also means that you will no
longer be able to plug an AT keyboard into a machine after it has
booted a GENERIC kernel and use it. AT keyboards aren't designed for
this anyway. USB keyboards are designed for this, and they work.
setting 'usbd_enable' in rc.conf during nwe installs if USB is detected.
Also, since usbd already handles USB mice automatically, note that the
mouse setup section in sysinstall only applies to non-USB mice.
stderr nodes. More specific items of this patch:
o Removed support for symbolic links, and the need for
fdesc_readlink().
o Put all the code from fdesc_attr() into fdesc_getattr() and removed
fdesc_attr(). This also made it easier to properly give all nodes
unique inode numbers.
o The removal of all non-fd nodes allowed the removal of the fdesc_read(),
fdesc_write(), and fdesc_ioctl() nodes, since we no longer have nodes
that get special handling.
o Correct the component name validity-checking in fdesc_lookup(). It
previously detected the end of the string by checking for a terminating
NUL, now it uses cnp->cn_namelen.
o Handle kqueue files as FIFOs. This is probably the closest file type
to represent this type of file there is, and it is unfortunately not
very representative of a kqueue. Creation time is not supported by
kqueue, so ctime, mtime and atime are all set to the current time when
getattr() was called.
o Also set st_[mca]time to the current time since there's no data in
socket structures that can be used to fill this in (FIFOs).
o Simplify fdesc_readdir() since it only has to report the numbered
fd nodes. Add `.' and `..' directory links as well.
o Remove read bits from directories as they tend to confuse programs
like tar(1).
