itojun 40606ab8f2 switch from kame-based m_aux mbuf auxiliary data, to openbsd m_tag 
implementation.  it will simplify porting across *bsd (such as kame/altq),
and make us more synchronized.  from Joel Wilsson

martin 501da0e586 In do not call pppoe_abort_connect if we fail to send the initial PADI 
packet - there is nothing to abort.
In pppoe_abort_connect rearange state handling slightly to avoid calls
to the PPP LCP state machine get into an infinite recursion.

This should fix the symptoms of PR kern/19500, but does not touch the
real cause for the lossage described there.

chs 7d8622764c when there are multiple matches for the requested media, select the first 
matching instance rather than the last one.  this restores the behaviour
in the multiple-match case to what it was when all the drivers only allowed
instance 0 (and in particular, makes autonegotiation of the on-board fxp
on my DK440LX board work again by default, which has two PHYs that both
advertise "auto").  as discussed on tech-net.

jdolecek e0cc03a09b merge kqueue branch into -current 
kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk. 
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

martin adb5933cbb Apply patch from Todd Vierling in PR kern/17665: 
remove a test that has been obsoleted by the authentication failure
counter - enter slow retry mode always, not only if we already transfered
data successfully (the test was designed to disable retries when the
initial authentication setting was not correct, the auth failure counter
does this job better).

martin ac83580ea9 Add an option PPPOE_TERM_UNKNOWN_SESSIONS to forcefully disconnect sessions 
we don't know anything about with a PADT packet.

Use with care, this is pretty dangerous and will kill all userland PPPoE
implementations. Therefore it is not enabled by default nor added as
a commented out option to GENERIC kernels.

But it is highly usefull if you have a fixed IP, an ISP that does not use
LCP echo requests for link monitoring and you want to recover quickly after
a crash or otherwise ungracefull disconnect.

thorpej a180cee23b Pool deals fairly well with physical memory shortage, but it doesn't 
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.
