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.

are used onboard in most of the newer PCI-based sun4u machines
(cosmetic change as they were also already probed as generic OHCI
without this). Detect whether their intpin register is valid and
correct it if necessary, i.e. set the respective IVAR to the right
value for allocating the IRQ resource, as some of them come up
having it set to 0 (mainly those used in Blade 100 and the first
one on AX1105 boards). This fixes attaching affected controllers.
Correcting the intpin value might be better off in the PCI code
via a quirk table but on the other hand gem(4) and hem(4) also
correct it themselves and at least for the USB controller part
the intpin register is truely hardwired to 0 and can't be changed.
This means that we would have to hook up the quirk information
in a lot of places in the PCI code (i.e. whenever the value of the
intpin register is read from or written to the pci_devinfo of the
respective device) in order to do it the right way.

do not attempt to start the same transfer twice, and it allows
ucomstop() to skip the restarting of the read pipe if it was not
originally running, such as when called indirectly from ucomreadcb().

This ensures that we explore EHCI busses before their companion
controllers' busses, so that ports connected to full/low speed
devices will be properly routed to the companion controllers by the
time the OHCI/UHCI exploration occurs.

media status change.
Looks like some of register writes in this functions mess up PHY interface.
No visible regressions has been found after commenting this code out -
the card properly handles forceful local mode changes and auto-detects changes
made remotely (tested with Auto, 10HD, 10FD, 100HD, 100FD).

transfer timed out, another thread could come along and attempt to
abort the same transfer while the timeout task was sleeping in
the *_abort_xfer() function.
Add an "aborting" flag to the private transfer state in each host
controller driver and use this to ensure that the abort is only
executed once. Also prioritise normal abort requests over timeouts
so that the callback is always given a status of USB_CANCELLED even
if the timeout-initiated abort began first.
The crashes caused by this bug were mainly reported in connection

not explore ohci or uhci busses before the companion echi controller
has been initialised, so it should fix the problem of multi-speed
USB devices getting attached as USB 1 devices first and then
re-attached as USB 2.
Some further changes are needed on architectures that do not currently
allow hooks to be inserted before configure_final() - alpha, ia64,
powerpc and sparc64. On these architectures the exploration will
now be delayed until the usb kthread runs.

Ignore these error bits, and instead use the HALTED bit to determine
if the transfer failed. Also update the USBD_STALLED detection to
ignore these bits.

then immediately overwriting the "next" pointers. Oops. Also
initialise qh_endphub, since the EHCI spec says that we should
always set the pipe multiplier field to something sensible.
This appears to make basic split transactions work, so enable split
transactions for control, bulk and interrupt pipes (split isochronous
transfers are not yet implemented). It should now be possible to
use USB1 devices even when they are connected through a USB2 hub.
