and the X1034A (quad HME; QFE) cards the X1033A (single HME) don't have a
PCI-PCI-bridge so we can't rely on the PCI slot number being useable as
index for the network address to read from the VPD on the latter. Use
the end tag to determine whether it is a QFE VPD with 4 NAs and only use
the slot number as index in this case.
- Remove a useless check.

without Open Firmware:
- The PCI data structure of some HME PROMs contains a non-zero interface
revision in the class code. Thus remove the checks for matching class
code and PCI data structure length and revsion. These were pretty much
useless anyway as we only really need the pointer to the VPD which is
located before the structure length and revision fields.
- On Sun QFE (Quad FastEthernet) cards read the Nth MAC-address for the
Nth HME controller instead of always the first one for all four HMEs. [1]
- Improve the comment describing the used VPD format to better reflect
reality.
- Minor clean-up.

- Let hme_start()/hme_init() acquire lock and then call
hme_start_locked()/hme_init_locked() respectivly.
- Teardown interrupt handler before hme_detach().
- Remove IFF_NEEDSGIANT flag and mark interrupt handler INTR_MPSAFE.
- Set callout handler to CALLOUT_MPSAFE.
- Add locks in hme MII interface.

without Open Firmware directly instead of using OF_getetheraddr(). This is
a bit painful though, as the MAC address is contained in the NA field of
the VPD of the EBus bridge, which is is another function of the same chip.
To make it worse, the VPD of the EBus bridge can't be accessed via the PCI
capability pointer but has to be digged out from the Boot PROM and has a
non-standard format.
The PCI VPD struct and macros used here should be part of the FreeBSD PCI
code nevertheless.

- 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.)
- 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
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).
