31144d9976 Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command".  ERESTART is -1, which can lead to
confusion.  ERESTART has been moved to -3 and EPASSTHROUGH has been
placed at -4.  No ioctl code should now return -1 anywhere.  The
ioctl() system call is now properly restartable.

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.

d1f0e4f6e4 Don't call if_alloc_sadl when creating the pppoe interface, it's called
from sppp_attach.
When destroying the interface, call sppp_detach for proper cleanup.
This avoids a crash from the slow timeout handler for no longer existing
interfaces (spotted by Rémi Zara).

b7c46d6199 use ALIGNED_POINTER() instead of ALIGN().
The type of ALIGN() is vary on architecture and casting pointer to u_int
is incorrect for MI code.
Since the code is to make sure aligned access to IP header and requires
bcopy if the test fails.  So the performance implication is not necessary
and we can use ALIGNED_POINTER() here.

aebd449baa Fix for FH infrastructure mode.
XXX: FH chanset should be calculated by FH hop pattern, but BayStack 650 AP
     always specify chanset to fixed value 1.  The previous code try to this
     hack into awi driver, but it is insufficient because the chanset value
     in awi driver may change while scan and it may be different from the
     value in receiving beacon/probe-response.  So we save encoded FH chanset
     into channel in 802.11 common bss information for now.

6a617566bc Move IEEE 802.11 MAC management functions from awi driver to
if_ieee80211subr.c, which can be shared between any IEEE 802.11
drivers.
However, most of current working IEEE 802.11b wireless LAN cards
have rich firmware and we cannot have a control to management frames
for such cards.

IBSS creation is now supported for the awi driver.

5ddc1e1310 Add retry mechanisms for Econet, so that if a four-way handshake doesn't
complete for some reason, we defer it for a bit and then try again.  This
gets ping down to 0% packet loss.

Of course, ping _should_ have been at 0% packet loss anyway, and that's the
next thing to deal with.

d679590033 Split the pre-computed ifnet checksum flags into Tx and Rx directions.
Add capabilities bits that indicate an interface can only perform
in-bound TCPv4 or UDPv4 checksums.  There is at least one Gig-E chip
for which this is true (Level One LXT-1001), and this is also the
case for the Intel i82559 10/100 Ethernet chips.

33d596bef8 Add support for incoming IP broadcast packets. The protocol for this is
worked out by observing RISC iX's behaviour, so it may be technically
wrong.  The only implementations of IP-over-Econet for which I've got
sources don't support broadcasts.

Tested using broadcast ping from RISC iX to NetBSD, and using rwhod.

0f810d8948 eco_input():
Use m_copydata() to preserve the Econet header, so we don't depend on
  notionally-unused areas of an mbuf remaining untouched.
  Check that ARP-over-Econet requests are exactly eight bytes long.
  Use m_pullup() before trusting mtod().

Between them, these make reception of unicast ARP responses work properly.
