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.

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.)

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

f7cbf2b00e Use a module name of 'if_lnc' in both the PCI and ISA sections of
the driver. Doing this breaks the ability to unload the unneeded
parts of the driver (e.g unload the PCI section when using an ISA
card), but currently ifconfig(8) expects an interface `XXX' to have
a driver name of `if_XXX'.

783e9b1a7a There were a few changes missed when this file was converted to
newbus in revision 1.19. As a result, lnc was, I believe, broken
for all PCI cards. The softc fields `lnc_btag' and `lnc_bhandle'
were not initialised, `rap', `rdp' and `bdp' were initialised to
the wrong values, and the size of the DMA ring memory was calculated
incorrectly.

Paul Richards has further cleanups in the pipeline, but this at
least is enough to make the driver usable with VMware.

46783fb897 Remove NBPF conditionality of bpf calls in most of our network drivers.
This means that we will not have to have a bpf and a non-bpf version
of our driver modules.

This does not open any security hole, because the bpf core isn't loadable

The drivers left unchanged are the "cross platform" drivers where the respective
maintainers are urged to DTRT, whatever that may be.

Add a couple of missing FreeBSD tags.
