so that PHY instance is not siginificant in ifmedia_match(). This
is done to support multiple PHYs on the MII. Without this change,
ifmedia_set() would panic the system when no PHYs were matched.
I ran into this on an AMD EasyNow PC, which is built around SiS
system chips with an embedded SiS 900 core, and an external AMD
Am79c901 PHY, which presents two PHYs on the MII: one for HomePNA,
and one for standard 10base-T. The 10base-T PHY ends up with instance
number 1...
* IPKDB_NE_PCISLOT does not need any dependencies (it is merely a
required parameter for IPKDB_NE_PCI).
* IPKDB_NE_PCI does should not have an option-dependency on IPKDB_NE_PCISLOT.
While IPKDB_NE_PCISLOT is a required parameter, that is not how option-
dependencies work, and we don't want IPKDB_NE_PCI to imply IPKDB_NE_PCISLOT,
as that would cause a bogus value for IPKDB_NE_PCISLOT to be used.
Also, the IPKDB_NE_PCI selector should be lower-case; make it so.

Setup sequence obtained from Krups OFW with some CyberPro-specific
magic from Linux driver. The driver still has a lot of hardcoded
stuff, but it is useful enough to bring up wscons on netwinder.

This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.

to enable 64-bit data transfers on 64-bit cards when plugged into
a 64-bit slot. Right know the Asante GigaNIX is listed in that
table.
Sigh, there is an EEPROM bit that can be used to detect 64-bit vs
32-bit cards. Unfortunately, at least 2 vendors of 32-bit cards
fail to clear the "DATA64_EN" bit in the EEPROM, which causes the
card to lose badly, because it still manages to detect that it's
plugged into a 64-bit PCI slot. Yay, stupid hardware vendors.

giving ownership of the frist descriptor to the chip, do it after
sync'ing all the descriptors for a single packet.
* Get CFG_M64ADDR, CFG_T64ADDR, and CFG_DATA64_EN from the EEPROM.
Note, we still disable CFG_M64ADDR and CFG_T64ADDR later (XXX need

disabled in the EEPROM. Make sure CFG_DATA64_EN is disabled if
we're not in a 64-bit slot.
-treat the builtin font like any other font at runtime
-for that, copy it to malloc()'d memory during attach()
-in early console initialization, if we have to consider a broken card

found on many (all?) of PCI-based ATI graphics cards. It is fully optional

Afaik quite a number of ATI chips suffers from the "loaded fonts don't
work" problem - these should be added.
Bad side effect of my change: The builtin font will be kicked out
always if a VGA_CONSOLE_SCREENTYPE is specified which needs a loaded
font. In early console initialization, we don't know much about the
graphics card, so we have to assume the worst (ie ATI:-).

Using pdc202xx_setup_channel() for PDC20268 and newer is wrong, and will

pointed out by Makoto Fujiwara on port-macppc.
Reenable statistics interrupts, reading it as 16bit caused it to not be cleared,and thus the eventual interrupt to not be cleared (and this caused an
infinite loop in interrupt routine).
While I'm there count STE_CarrierSenseErrors as oerror (this is incremented
each time we try to send a packet and the link is down).
- when a transmit underrun occurs, only reset the transmit logic. This prevents
the link from going down at the MII level (the same logic can probably
be used for other transmit errors)
- set the urgent threshold to half the start threshold. From experiments
this helps a bit decreasing the number of underruns
Now that underruns don't cause the interface to stop for several seconds,
make back out the default transmit threshold to 128.
- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other

- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
cause the link to go down for several seconds on my Dlink DFE580-TX (quad-port
DL1002). This behavior is unacceptable, especially as the driver usually
gets several underrun at once, causing the link to be almost unaviable
for several 10s of seconds.
Bump the default transmit threshold to 1504 bytes to avoid transmit underrun.
is down cause the chip to create an IE_UpdateStats condition which can't be

- mute the volume for interrupt channel
- add some improvements for device initialization

pci-pci bridge (and thus needs its interrupts "swizzled").
Formerly, pci_probe_device() assumed pci busses other than bus zero
were bridged; however, much recent x86 hardware supports multiple
primary pci busses differently -- there is a system-wide bus numbering
scheme. Now, we instead look at the (newly introduced) sc_bridgetag
value in the parent bus to figure out if there's a ppb or equivalent
in the way.
This fixed at least one case where the i386 MP branch gets interrupt
mapping wrong.
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
for a device into two functions:
* pci_probe_device() actually probes/attaches the device specified
by the provide pcitag_t.
* pci_enumerate_bus() enumerates the bus, and calls pci_probe_device()
for each device on the bus. A pci_enumerate_bus_generic() is provided
which implements the old method of doing this: If something found at
dev0/func0, determine number of functions and probe each one.
Machine-dependent code will be able to specify the bus enumeration
routine in the future.
* Garbage-collect some unused stuff.
* Make the Tx window slide along the Tx job queue space, not the
Tx descriptor space. We are more likely to run low on DMA maps
than we are hardware descriptors.
* When forcing an interrupt, make sure that interrupt-delay-enable is
cleared (necessary with last change to make sure it's set for all
descriptors).
* Crank up the Transmit Interrupt Delay Value to 1024 * 1.024 msec. We
really want these to be deferred.
context setup.
* Implement Matt Thomas's sliding Tx interrupt window algorithm,
forcing an interrupt when the Tx desc list is 2/3 consumed.
* Use the Report Packet Sent interrupt, rather than Report Status,
since we use the Tx descriptor to count Tx errors.
errors for narrow transfers after a reselect. FreeBSD sym driver has a comment
about this, but their workaround (disable SCSI gross error reports) doesn't
work for me. Instead dissallow disconnect if the target is not wide
(FreeBSD doens't allow disconnect until the target has been fully probed, which
is why they may not have noticed my problem).
transmit and receive descriptor rings is limited to 256 descriptors.
So, set the if_snd queue length to 256 to let the upper layers queue
lots of packets, and let the driver handle up to 32 of them at a time.
(We should probably make this change to most Ethernet drivers, since
it actually saves some resources.)
* Increase the number of Tx DMA segments from 8 to 16.
* Clean up the way we count "how many times did I get a packet with N
DMA segments".
* Add a missing htole32() in wm_tx_cksum().
* Don't set both RS and RPS in the last Tx descriptor of a packet; just
use RS.
* Add some more information to the watchdog message.
so that they're more useful for arbitrary types of external storage:
* Add an "mbuf *" argument to (*ext_free)(). If non-NULL, (*ext_free)()
is expected to free the mbuf itself. This allows (*ext_free)() to use
the mbuf for bookkeeping (e.g. deferring the work to a helper thread).
If the "mbuf *" argument is NULL, we are assumed to be in a context
which is safe for performing the destructor operation *now*.
* Adjust MEXTREMOVE() and MFREE() routines for above change.
* Update "ade" and "ti" drivers for new semantics.

Note that DT transfers are not enabled for 53c1010-33 rev 0 yet; if I trust

yet.
If is restricted to SIOP which implement the load/store instruction, and
has 10 scratch registers (basically, 825 and newer, possibly 770).
It implements a different interface between host and script, using a real
ring for command starts, and improved support for reconnect which will allow
256 tag per device. It uses interrupt on the fly to signal complete command,
which allows several commands to be serviced per interrupt and doesn't require
the script to stop to signal command completion.
So to disable them all better use 0xff instead of 0x00 as mask. Noted
by Matthias Drochner.
Move some initialization unrelated to interrupts back to its place at
attach time.
