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.

aaa160f357 bus_dmamap_sync() overhaul:
- Remove NetBSD-style or-ed together BUS_DMASYNC operations, in some
  cases relaxing the (intended) syncing operation a bit.
- Add syncs before reading the descriptor rings.
- Try to combine syncs where possible to avoid overhead.
- Sync all maps before unloading them.

195530b9dd Convert to use bus_dmamap_load_mbuf(); decouple software TX descriptors
from the hardware descriptors to avoid the overhead of having a DMA
map for each of them. Bump the number of hardware descriptors to 128,
and use half as many software descriptors for now.
Some minor cleanups.

673d91916d network interface driver changes:
o don't strip the Ethernet header from inbound packets; pass packets
  up the stack intact (required significant changes to some drivers)
o reference common definitions in net/ethernet.h (e.g. ETHER_ALIGN)
o track ether_ifattach/ether_ifdetach API changes
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

9f6388ba93 Miscellaneous fixes:
- always reinitialize the rx descriptors, even if the mbuf is kept.
  This should fix the hangs on ifconfig that were observed
- on an rx overflow, reinitialize the descriptor so that the interface
  will not hang
- correct some bus_dmamap_sync() calls
- correct some debug messages
- some minor nits

<sys/endian.h>.  This puts us in line with NetBSD and OpenBSD.

7ee69ef245 Assorted fixes:
- remove some useless code from the status change handler that was intended
  to enable the the MII drivers for external phys; this is already done
  during interface initialization, and the deleted code made some
  assumptions about phy addresses that do not seem to hold true on newer
  cards. This should get at least one of the two hmes of newer Netra t1
  machines working.
- correct the interrupt resource allocation
- bump the number of RX descriptors, lower values cause promblems on some
  machines

52381bfae4 Add a driver for the Sun HME PCI/SBus ethernet adaptor, which is onboard
in most machines of the Sun Ultra series. This is a port of the NetBSD
driver which I enhanced to make use of the gather functionality and the
configurable RX buffer offset to avoid copying all received/sent packet
(instead, packets will be directly DMAd from mbuf chains and into mbuf
clusters now).
