Take a step towards removing if_watchdog/if_timer. Don't explicitly set
if_watchdog/if_timer to NULL/0 when initializing an ifnet. if_alloc()

Give MEXTADD() another argument to make both void pointers to the
free function controlable, instead of passing the KVA of the buffer
storage as the first argument.

Fix all conventional users of the API to pass the KVA of the buffer
as the first argument, to make this a no-op commit.

Likely break the only non-convetional user of the API, after informing
the relevant committer.

Update the mbuf(9) manual page, which was already out of sync on
this point.

Bump __FreeBSD_version to 800016 as there is no way to tell how
many arguments a CPP macro needs any other way.

This paves the way for giving sendfile(9) a way to wait for the
passed storage to have been accessed before returning.

This does not affect the memory layout or size of mbufs.

Parental oversight by: sam and rwatson.

No MFC is anticipated.

Replace m_extadd() with macro version MEXTADD().

Fix "struct ifnet" leak if attach() fails in the middle.

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags. Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags. This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

Fix another fallout from the ifnet change that assumed that a softc
starts with an ifatm which in turns has an ifnet. Remove also a couple
of unneccessary casts that could hide such things in the future.

Approved by: re

Stop embedding struct ifnet at the top of driver softcs. Instead the
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
from driver private storage rather than sometimes being ac_enaddr.

Eliminate multiple __FBSDID and sys/cdefs.h.

All three of these drivers abused cv_waitq_empty in the same way by spinning
on it in hopes of making sure that the waitq was empty before going on.
This wasn't needed and probably never would have worked as intended. Now
that cv_waitq_empty() and friends are gone, the code in these drivers that
spins on it can go away too. This should unbreak LINT.

Change instances of callout_init that specify MPSAFE behaviour to

does not change the behaviour; it just makes the intent more clear.

Make open channels persist across ifconfig down and up. All channels
that are not currently closing when the interface is configured down

Remove the ATMIOCENA and ATMIOCDIS ioctl. Everyting has been converted

This is a driver for IDT77252 based ATM interfaces. It has been tested
with a ProATM-155 and an IDT evaluation board and should also work
with a ProATM-25 (it seems to work at least, I cannot really measure
what the card emits). The driver has been tested on i386 and sparc64,
but should work an other archs also. It supports UBR, CBR, ABR and VBR;
AAL0, AAL5 and AALraw. As an additional feature VCI/VPI 0/0 can be
opened for receiving in AALraw mode and receives all cells not claimed
by other open VCs (even cells with invalid GFC, VPI and VCI fields and
OAM cells).

my questions.
