Instead, continue on to the next device. The normal fd probe will take

* Some systems have _FDE but no child devices in AML. For these, add a
second pass that compares the results of _FDE to the presence of devices.
If not present, add the missing device.
* Some BIOS authors didn't read the spec. They use tape drive values for

Make the PCI and PCCARD attachments provide a bus_get_resource_list()
method so that resource listing for PCCARD works. PCCARD does not
have a bus_get_resource_list() method (yet), so I faked up the
resource list management in if_ndis_pccard.c, and added
bus_get_resource_list() methods to both if_ndis_pccard.c and if_ndis_pci.c.
The one in the PCI attechment just hands off to the PCI bus code.
The difference is transparent to the NDIS resource handler code.
Fixed ndis_open_file() so that opening files which live on NFS

Turn subr_ndis.c:my_strcasecmp() into ndis_strcasecmp() and export

step in making this driver more attachment neutral. Others plan on
adding acpi front ends.
Still need to cleanup the MI part of the driver because it isn't as
bus independent as it could be.
- In subr_ndis.c:ndis_allocate_sharemem(), create the busdma tags
used for shared memory allocations with a lowaddr of 0x3E7FFFFF.
This forces the buffers to be mapped to physical/bus addresses within
the first 1GB of physical memory. It seems that at least one card
(Linksys Instant Wireless PCI V2.7) depends on this behavior. I
don't know if this is a hardware restriction, or if the NDIS
driver for this card is truncating the addresses itself, but using
physical/bus addresses beyong the 1GB limit causes initialization
failures.
- Create am NDIS_INITIALIZED() macro in if_ndisvar.h and use it in
if_ndis.c to test whether the device has been initialized rather
than checking for the presence of the IFF_UP flag in if_flags.
While debugging the previous problem, I noticed that bringing
up the device would always produce failures from ndis_setmulti().
It turns out that the following steps now occur during device
initialization:
- IFF_UP flag is set in if_flags
- ifp->if_ioctl() called with SIOCSIFADDR (which we don't handle)
- ifp->if_ioctl() called with SIOCADDMULTI
- ifp->if_ioctl() called with SIOCADDMULTI (again)
- ifp->if_ioctl() called with SIOCADDMULTI (yet again)
- ifp->if_ioctl() called with SIOCSIFFLAGS
Setting the receive filter and multicast filters can only be done
when the underlying NDIS driver has been initialized, which is done
by ifp->if_init(). However, we don't call ifp->if_init() until
ifp->if_ioctl() is called with SIOCSIFFLAGS and IFF_UP has been
set. It appears that now, the network stack tries to add multicast
addresses to interface's filter before those steps occur. Normally,
ndis_setmulti() would trap this condition by checking for the IFF_UP
flag, but the network code has in fact set this flag already, so
ndis_setmulti() is fooled into thinking the interface has been
initialized when it really hasn't.
It turns out this is usually harmless because the ifp->if_init()
routine (in this case ndis_init()) will set up the multicast
filter when it initializes the hardware anyway, and the underlying
routines (ndis_get_info()/ndis_set_info()) know that the driver/NIC
haven't been initialized yet, but you end up spurious error messages
on the console all the time.
Something tells me this new behavior isn't really correct. I think
the intention was to fix it so that ifp->if_init() is only called
once when we ifconfig an interface up, but the end result seems a
little bogus: the change of the IFF_UP flag should be propagated
down to the driver before calling any other ioctl() that might actually
require the hardware to be up and running.
device is open. This allows certain old and rather special dual
floppy controllers to work on both channels, as long as you only
