76039bc84f The r48589 promised to remove implicit inclusion of if_var.h soon. Prepare
to this event, adding if_var.h to files that do need it. Also, include
all includes that now are included due to implicit pollution via if_var.h

13f4c340ae 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.

4df70a92b5 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.

fc74a9f93a 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.

8e994188e2 When compiled with debugging trace the number of transmit mbufs that
we own. Warn if something strange happens (number drops below zero or
there appears to be a leak).

d976286c77 Allow sending of more than one raw cell from a single mbuf. Only the
very first cell in the mbuf should have a cell header word (of which
everything except the payload type and the CLP bit is ignored). All
other cells should be 48 byte and get the same header as the first cell.

This fixes a problem with sending more than 120000 raw cells/sec through
an HE155. The card seems to need 2 cell times to DMA the transmit buffer
ready queue entry and the transmit buffer descriptor so at 1/3 the
link rate the transmit buffer ready queue starts to fill up. Even with this
patch it's obviously impossible to send raw cells at link rate.

77e6a3b2dd Prefer new location of pci include files (which have only been in the
tree for two or more years now), except in a few places where there's
code to be compatible with older versions of FreeBSD.

a80f653574 Make the driver preserve open connections accross ifconfig down
and up commands. When configuring the interface down only the
connections that are currently closing are deleted from the connection
table. When the interface is configured up, all connections that
are in the table are re-opened.

445b5e54cf Use the default arguments for lockfunc and lockfuncarg in
bus_dma_tag_create. We need to be sure that our packets are
kept in-sequence (that's how ATM is supposed to work) and
therefor use BUS_DMA_NOWAIT in all calls to bus_dmamap_load.

For memory allocated with bus_dmamem_alloc the use of anything
other than NULL arguments for the locking is anyway bogus because
this memory never should need bouncing and hence the load should never
be defered.

Allow the receipt of OAM and RM cells on raw connections. Caveat: it seems
that RM cells are still processed by the hardware even when we open the
connection as UBR.
