alix/net5501 with and without software vlan tagging, also with NFS (v2, v3,
UDP, TCP). Not used on earlier chips and does not introduce problems on
original EPIA board.
From chris@, based on enhancements in the FreeBSD driver.
"put it in then" dlg@, looks good to claudio@.

from the oldest vt86c100a datasheet to the newest vt6105m. FreeBSD
indicates that it is more reliable than VR_RXSTAT_ERR for detecting
error conditions, that its use results in less incorrectly dropped
packets). From chris@.

no binary change.

- add HWTAG capability to the quirks table. not yet used.
from chris@. no functional change.

- avoid the need for unnecessary mbuf copies on modern vr(4) devices
(ancient ones required longword-alignment, but this has not been the case
for several generations now). reduces cpu time, particularly for forwarded
traffic.
from chris@. tested by chris@, myself, Emilio Perea on various devices
including original VIA EPIA, Soekris net5501, pcengines.ch ALIX.

state change. Workaround by resetting the chip if necessary.
Also do not try to send packets if our link is down, as this triggers
watchdog timeouts. While there correct the VR_RXSTAT_RX_OK define
(not used yet). Changes inspired from FreeBSDs overhauled vr(4).

Move calling ether_ioctl() from the top of the ioctl function, which
at the moment does absolutely nothing, to the default switch case.
Thus allowing drivers to define their own ioctl handlers and then
falling back on ether_ioctl(). The only functional change this results
in at the moment is having all Ethernet drivers returning the proper
errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown
ioctl's.

If the RX path runs into an out of mbuf scenario, the code
will leave the RX chain with a NULL'd mbuf-slot.
We now always reassign a valid mbuf, even if m_devget() fails.

Really just the low-hanging fruit of (hopefully) forthcoming timeout
conversions.

o On non-strict alignment archs, dont copy the mbuf, every time, unload it, and send
it up the stack and just get a new one for the rx ring. We still do the copy on
strict alignment archs though...
o create a function to handle mbuf allocation for the rx ring, vr_mbuf_alloc(),
use it to allocate the mbufs and shuffle the bus dma setup around.

is found to have PCI power management capability. It has been
found that unconditionally touching this register with the original
VIA Rhine chipset, which does not have power management capability,
and due to the shorter width of the IO addess space, it is possible
for the vr(4) driver to do bad things with hw with IO address space
adjacent to a vr(4) adapter.
Tested by a few users, brad@ and jmc@.
