device pointers. They don't change as the children device drivers
come and go. Rather, check to see if the device is attached where we
would have checked ! NULL. This solves many asymmetries in the code
that likely could lead to crashes when loading/unloading cbb without
one or more of the expected children's driver not present.
o When detaching all children, try really hard to get all the children
list before giving up. This is based on an observation by hans petter
selasky in his usb p4 branch.
o When rescanning devices after a driver is added, abort if we can't get
the child list with a message.
o when rescanning devices, if the reprobe/attach is successful, save the
device for cardbus/pccard.
Unlike other GigEs Yukon II always set VLAN bit when it detects VLAN
tagged packet regardless of H/W VLAN processing configuration state.
So it need to check IFCAP_VLAN_HWTAGGING bit to know whether driver
is configured to take advantage of H/W VLAN processing. If H/W VLAN
processing was disabled don't adjust received packet length such that
subsequent validation logic works for software VLAN processing.

blacklist a bunch of old chipsets. If a system contains a PCI-PCI bridge
that supports PCI-X, assume the chipset supports PCI-X. If a system
contains a PCI-express root port, assume the chipset supports PCI-express.
If the chipset doesn't support either PCI-X or PCI-express, then blacklist
it by default. We should now only need to explicitly blacklist PCI-X or
PCI-express chipsets that don't properly handle MSI.

- Fix a cosmetic nit in the bootverbose printf in pci_alloc_msix_method().
Bugfix for the Realtek PHY driver... an RTL8201L standalone PHY
needs different handling than the integrated ones in terms of
speed detection. There was a bogus test based on the parent
device driver name string controlling which speed register to
query. That test began failing when the rl driver was split into
separate rl and re drivers some time ago. Apparently nobody ever
noticed because the buggy code only executes if NWAY negotiation
failed. Since we happen to be testing with an ancient dumb hub
rather than a modern switch, we found it.
To fix it all, have the attach() routine notice whether we're
dealing with an integrated PHY or an RTL8201L and store that info
in a struct accessible to the status() routine that needs to know
which register to query.
I touched up the fixes because they were relative to RELENG_6 and to
bring a few nits into line with style(9).

tunable allowing automatic parsing of VPD data to be disabled. The
default is left as-is; if you are having problems with hard hangs at boot
due to VPD, try setting hw.pci.enable_vpd=0. A proper architectural
solution has been under discussion for some time, but this allows me to
boot my test machines in the mean time.

PR/108719, but there's a simpler fix: free it after it is used, and
then get rid of the redundant frees this causes. Other leaks in this
PR not yet fixed.
While I'm here, remove NetBSD/OpenBSD code and some of the portability
#defines that were getting in the way of understanding this code. The
devinfo bug was harder to spot because one needed to know that
device_set_desc_copy() was used inside of one of them (one that didn't
take an argument!).
Prefer device_printf(sc->sc_dev, "...") to printf("%s:...",
device_get_nameunit(sc->sc_dev)). This saves almost 300 bytes.

sndbuf_free(). For a managed buffer (mostly hw specific managed buffer),
either provide CHANNEL_FREE() method with appropriate return value to
invoke semi-automatic sndbuf_free() or simply do it on their own. If
everything is failed, sndbuf_destroy() will come to the rescue as a
final measure.
