This commit was manufactured to restore the state of the 6.0-RELEASE image.

Stop embedding struct ifnet at the top of driver softcs. Instead the

2005-06-10T16:49:24+00:00

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.

Use contigmalloc() and contigfree() instead of vm_page_alloc_contig() and

2004-01-13T20:36:03+00:00

kmem_free().  Note: The FreeBSD-specific code in this file has been
subsumed by the FreeBSD-specific header file, pdq_freebsd.h.  That header
file already specifies the use of contigmalloc() and contigfree().  Thus,
the purpose of this change is to avoid having nonsensical examples of
FreeBSD-specific memory allocation in our source tree.

Replace the if_name and if_unit members of struct ifnet with new members

2003-10-31T18:32:15+00:00

if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

- Merge the pdq driver (if_fpa and if_fea) from NetBSD.

2002-03-29T11:22:22+00:00

  Among other things this gets us ifmedia support.
- Update fddi_ifattach() to take an additional argument.

Undo part of the tangle of having sys/lock.h and sys/mutex.h included in

2001-05-01T08:13:21+00:00

other "system" header files.

Also help the deprecation of lockmgr.h by making it a sub-include of
sys/lock.h and removing sys/lockmgr.h form kernel .c files.

Sort sys/*.h includes where possible in affected files.

make PCI DEFPA fiddi adapters work on alpha:

2001-01-08T21:04:33+00:00

- add a dma hack similar to the NetBSD one
- change PDQ_OS_MEM{RD,WR} to use readl/writel rather than deref'ing
	a 32 bit va.

Note that I did just enough to get this working on alpha.  I probably
should have updated it to use busspace, but I was too lazy to navigate
the twisty minefield of ifdefs that make up this driver.
