- In ULCK_BUF we no longer need to acquire the lock, just write the buf out.
- The combination of these changes eliminates one more use of B_LOCKED which
is in the way of making the buffer cache SMP safe. In the long term
ext2fs should probably not try to optimize the use of their metadata bufs
with a private cache. This will starve the rest of the system for buffers
in the extreme case.
Discussed with: bde (A long time ago..)
Tested on: md disk/x86
Bug Fixes:
- Allow users to use LAA
- Remember promiscuous mode settings while bridging
- Allow gratuitous arp's to be sent

METEORSSIGNAL ioctl. Applications use this ioctl with the value
METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery,
but revision 1.126 caused the driver to return EINVAL in this case.
Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses
0 to reset signal delivery.
This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the
bktr driver, and restructures the code a bit so that it is otherwise
identical between the bktr and meteor drivers.
returned mbuf can be NULL. Check for NULL in rip_output() when
prepending an IP header. This prevents mbuf exhaustion from
causing a local kernel panic when sending raw IP packets.

compatibility routine, go ahead and accept that as 'success'. A
properly written compatible driver should return < 0 for both the
compat match and compat probe routines, so this will wind up doing the
right thing.
/usr/include/osreldate.h doesn't exist on the system. While this
could be worked around by saying something like 'make includes
OSLRELDATE=0' when this file doesn't exist, it is just as easy to
provide a fallback when the file we know we depend on doesn't exist.
While this doesn't make all targets work w/o a
/usr/include/osreldate.h, because some of the FreeBSD bootstrap tools
use this file. 'make includes' however does work.

This will get rid of the warnings issued at shutdown (that seems to
worry alot of users), but will also no flush cache on lots of
devices that can, but doesn't set the right support bits...
