the driver to issue a bus reset more quickly than intended. We want to
wait if we find another SCB that could be the cause of this timeout,
not proceed to a bus reset.
This code is currently inside an #ifdef 0/#endif pair.

a chance to process all pending packets, otherwise the chip may overwrite
their mbuf clusters after we have freed them.
Eliminates a race that can cause random pool corruption when reconfiguring
an interface under heavy network load.

Ignore CSR13, CSR14, CSR15 'Media Specific Data' registers
for 21143 based cards which use SIA mode.
This fixes 10mbit mode for ZNYX ZX346Q cards and other
21143 based cards.
rev 1.108
Only use a SIA/SYM media info block if no MII block is detected.
The submitter of PR 32118 told me that this patch also fixes autoselecting
for znyx 4 port cards (10baseT, 100baseTX did work already).

line and zero line functions. Fix a potential bug
(ahd_set_transaction_status was used where ahd_set_scsi_status was
intended) inside a currently #ifdef 0/#endif section of code.
No functional changes intended except for a bit of extra locking via
ahd_list_lock*.

Do not call mii_pollstat() from within device tick routines; the status
information is updated by mii_tick().
dcphy.c rev 1.13
Work around an Intel 21143 chip bug.
Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick()
routine. dc_tick() is called regularly to detect link up and link down
status, especially when autonegotiating.
The expectation was that mii_tick() (which is still called from dc_tick())
would update status information automatically in all cases where it would
be sensible to do so.
Unfortunately, with authentic 21143 chips this is not the case, and
the driver never successfully autonegotiates. This is because (despite
what it says in the 21143 manual) the chip always claims that link is not
present while the autonegotiation enable bit is set. Autonegotation takes
place and succeeds, but the driver tests the link bits before it switches
off the autonegotiation enable bit, and success is not recognised.
The simplest solution is to call dcphy_status() more often for MII_TICK
calls by dropping out of the switch statement instead of exiting when
we are autonegotiating and link appears to not be present. When
autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx
state and turn off the autonegotiation enable bit. The next call to
dcphy_status() will notice that link is present, and the dc driver code
will be notified.
Macronix chips also use this code, but implement link detection as
described in the manual, and hence don't need this patch. However, tests
on a Macronix 98715AEC-C show that it does not adversely affect them.

the fallout from that. Ensure pcireg_t variables are being used with
pci_conf_read/write functions - found one uint16_t variable
(pcix_status) being used to store and restore (32 bit) pcireg_t
values.
Some KNF.
No functional changes.

binary-only hal module found in FreeBSD and NetBSD. OpenBSD's approach
is based on reverse engineering because it is _not_ possible to
include a non-free and binary-only piece of software in a 100% free
operating system. it still lacks some features found in the "official" hal
module but this will be done very soon with a help by a lot of
contributors - because it's free.

Fix the support for the AN985/983 chips, which do not set the
RXSTATE to STOPPED, but to WAIT. This should fix hangs which
could only be solved by replugging the cable.
