3a5aee5adc Clean up two printf()s that were on a line by themselves unintendedly
after the ethernet address printing was moved to common code.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
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.

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

18100346d1 Miscellaneous fixes:
- Fix compilation without GEM_DEBUG.
- Do not #define GEM_DEBUG by default; it adds overhead (due to bzero()ing
  RX space) and is not needed any more, since the driver is quite stable
  now.
- Fix watchdog timeouts when failing to load TX packets.
- Do not forcibly limit the number of descriptors used for a packet to
  GEM_NTXSEGS, by passing this number to bus_dma_tag_create(). There is
  no requirement for a limit any lower than the total number of
  available descriptors, and the present limit caused network problems
  due to mbuf chains requiring more descriptors.
  GEM_NTXSEGS is still used to estimate the interrupt window size, for
  which we just need an estimate.

533294b956 - Don't call pci_enable_io() in drivers (unless needed for resume).
- Don't test memory/port status and emit an error message; the PCI
  bus code will do this now.

f246e4a17f - Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
  such abuse isn't really needed.  (And if we do need type information
  associated with a module then we should make it explicit and not
  use hacks.)

b2d59f4234 bus_dmamap_sync() overhaul:
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
  cases relaxing the (intended) syncing operation a bit.
- Stop pretending that that we can sync part of a dmamap: replace the
  GEM_CDTXSYNC and GEM_CDRXSYNC macros with GEM_CDSYNC to sync the
  complete control map, and combine syncs wherever possible to avoid
  the overhead.
- Sync all maps before unloading them.
- Remove a few syncs which should be unnecessary.

o track bpf changes (use BPF_TAP and BPF_MTAP)
o track vlan changes (ifnet capabilities, revised processing scheme, etc.)
o use if_input to pass packets "up"
o call ether_ioctl for default handling of ioctls
