the standard.
1) When the bridge tells us that we have a card that isn't recognized, we
use the force register to force the CV_TEST to run. This test causes the
bridge to re-evaluate the card. Once this re-evaluation process happens,
we get a new interrupt that may say it is ready to process. We try this up
to 20 times. Tests have shown that this appears to correctly reset the
'Unknown card type' problem that I saw on my Sony PCG-505TS.
2) Take a page from OLDCARD and always read the CSC register in the ISR.
Some TI (and it seems maybe Ricoh) chipsets require this to behave
properly. This work around appears to work due to some power management
protocols that were improperly implemented. Maybe it can be removed when
this driver supports the full PME# protocol described in the standards.
3) Minor additional debug printf when debugging is enabled.
4) Minor additional commentary for things that are obvious only after study.
# I'm committing this from my Sony PCG-505TS using shared PCI interrupts
# and NEWCARD, but there are some issues with the Ricoh bridge still, but
# at least now I can boot with the card inserted and have it work.
a reference to the containing object. The purpose of the reference
being to prevent the destruction of the object and an attempt to free
the wired page. (Wired pages can't be freed.) Unfortunately, this
approach does not work. Some operations, like fork(2) that call
vm_object_split(), can move the wired page to a difference object,
thereby making the reference pointless and opening the possibility
of the wired page being freed.
A solution is to use vm_page_hold() in place of vm_page_wire(). Held
pages can be freed. They are moved to a special hold queue until the
hold is released.

PCG-505BX (for example) has one of those:

wi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
1) avoid immediately calling bzero() after malloc() by passing M_ZERO
2) do not initialize individual members of the global context to zero
3) remove an unused assignment of ifctx in bootpc_init()

that the MELCO's id should be 0x18a instead of 0x8a01. Fix this.

Disabled by default. To enable it, the new "options PIM" must be
added to the kernel configuration file (in addition to MROUTING):
options MROUTING # Multicast routing
options PIM # Protocol Independent Multicast
2. Add support for advanced multicast API setup/configuration and
extensibility.
3. Add support for kernel-level PIM Register encapsulation.
Disabled by default. Can be enabled by the advanced multicast API.
4. Implement a mechanism for "multicast bandwidth monitoring and upcalls".

caught this if semaphores were used more often in the kernel.

are in the table are re-opened.

Yes, _MC_FLAGS_KSE_SET_MBOX is a hack and I'm proud of it :-)
