struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.
This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.
Other changes of note:
- Struct arpcom is no longer referenced in normal interface code.
Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
To enforce this ac_enaddr has been renamed to _ac_enaddr.
- The second argument to ether_ifattach is now always the mac address

2) named the sysctl net.inet.ip.random_id
3) IPv6 flow IDs and fragment IDs are now always random.
Flow IDs and frag IDs are significantly less common in the
IPv6 world (ie. rarely generated per-packet), so there should
be smaller performance concerns.
The sysctl defaults to 0 (sequential IP IDs).

that "ifconfig stf" creates the interface stf rather then stf0 and

- Allow destroy functions to fail so they can refuse to delete
interfaces. Currently, we forbid the deletion of interfaces which
were created in the init function, particularly lo0, pflog0, and
pfsync0. In the case of lo0 this was a panic implementation so it
does not count as a user visiable change. :-)

ALTQ enabled versions of IFQ_* macros by default, as requested by serveral
others. This is a follow-up to the quick fix I committed yesterday which
turned off the ALTQ checks for non-ALTQ kernels.
rig a PREPEND macro for ALTQ as the POLL/DEQUEUE semantic is very bad in
terms of locking. We make this a full functional queue to allow "bulk
dequeue" which will further reduce the locking overhead (for non-altq
enabled devices). Drivers will access this via the following macros, which
will show up in <net/if_var.h> once we expose ALTQ to the build:
IFQ_DRV_DEQUEUE(ifq, m) - takes a mbuf off the queue (driver queue first)
IFQ_DRV_PREPEND(ifq, m) - pushes a mbuf back to the driver queue
IFQ_DRV_PURGE(ifq) - drops all packets in both queues
IFQ_DRV_IS_EMPTY(ifq) - checks for pending mbufs in either queue
One has to make sure that the first three are protected by a driver mutex.
At the moment most network drivers still require Giant, so this is not an
issue. Even those that have thier own mutex usually hold it in if_start and
the like, so this requirement is almost always satisfied.
This evolved from a discussion with Andrew Gallatin.

As people started wondering:
The strange path layout "altq/altq" is there to avoid "-Isys/contrib" and
