This can be caused by configurations including bridge, ppppoe or vlan but
no ethernet interfaces - which does not make sense. We should add a way
to config(8) to issue this kind of warnings.

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.
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.

Don't copy ttl from the inner packet to the encapsulating packet. Make
the outer ttl sysctl'able. This should close PR 14269 from Jasper Wallace
(change partly from there) and it makes traceroute work over gre tunnels.

Collect both local and remote address and set them to the interface in
one step (the peer adress was not set at all before).
This causes the peer address now to show up on the interface and all
messages to the routing socket to be send with correct data. The latter
has been the last missing piece to complete PPPoE support.

The type of ALIGN() is vary on architecture and casting pointer to u_int

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.

Of course, ping _should_ have been at 0% packet loss anyway, and that's the
