from NetBSD. This driver actually can replace lnc(4). Advantages over
lnc(4) are:
- Cleaner and more flexible regarding MD needs.
- Endian-clean and MPSAFE.
- Supports ALTQ, VLAN_MTU, ifmedia.
- Uses 32bit DMA for the PCI variants.
This commit includes front-ends for the dma(4) pseudo-bus found on SBus-
based sparc64 machines (thus supports the on-board LANCE in Sun Ultra 1)
and PCI. In order to actually replace lnc(4), the front-ends for ISA and
the PC98 CBUS would have to be added but for which I don't have hardware
to test.

Also call the mediachg function when we set flags UP and are already
running. If this were a pure ifmedia driver, we'd not need to do this
since we'd be ignoring the linkX flags.
This reduces the number of ifdefs to support sub-devices a little as a
nice side effect. It also reduces the number of hpp interfaces
exposed by 33%.
man page that the ifconfig option link2 is used to disable the AUI
transceiver on the 3com boards (should also say HP PC Lan+). This
makes the connection clearer.
Add a note about why we set this flag prior to attaching the device.
We never set or clear the flag later, only test it. There can be no
races here, but this might be asthetically displeasing to some. Also
note that we may no longer need to have this knob at all as we may be
able to do it with the more sophisticated rc.d scripts we have today I
think the only reason it is there is because we didn't used to allow
its proper setting when configured to get the IP address via DHCP.
I'll note that this would be better handled by using ifmedia for all
ed cards, not just those with a miibus...
This is important with MegaLib, when issuing a GET_REBUILD_PROG since
it returns an error if the drive is not in rebuild state.
