718724fd0d Fix I/O freezes in some cases, caused by r257916.
Delaying isp_reqodx update, we should be ready to update it every time
we read it.  Otherwise requests using several indexes may be requeued
ndefinitely without ever updating the variable.

65d08437ef Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.

96f9425f06 Add a tunable "hw.mfi.mrsas_enable" to allow mfi(4) to drop priority and
allow mrsas(4) from LSI to attach to newer LSI cards that are support by
mrsas(4).  If mrsas(4) is not loaded into the system at boot then mfi(4)
will always attach.  If a modified mrsas(4) is loaded in the system.  That
modification is return "-30" in it's probe since that is between
BUS_PROBE_DEFAULT and BUS_PROBE_LOW_PRIORITY.

This option is controller by a new probe flag "MFI_FLAGS_MRSAS" in mfi_ident
that denotes cards that should work with mrsas(4).  New entries that should
have this option.

This is the first step to get mrsas(4) checked into FreeBSD and to avoid
collision with people that use mrsas(4) from LSI.  Since mfi(4) takes
priority, then mrsas(4) users need to rebuild GENERIC.  Using the
.disabled="1" method doesn't work since that blocks attaching and the
probe gave it to mfi(4).

add35ed5b8 Follow r261352 by updating all drivers which are children of simplebus
to check the status property in their probe routines.

Simplebus used to only instantiate its children whose status="okay"
but that was improper behavior, fixed in r261352.  Now that it doesn't
check anymore and probes all its children; the children all have to
do the check because really only the children know how to properly
interpret their status property strings.

Right now all existing drivers only understand "okay" versus something-
that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

e4be5a1636 Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to
process "status" properties of OF nodes.

I've avoided adding new KOBJ methods here so that we don't have to modify
every ofw_bus in the tree. Since 100% of implementations of ofw_bus use
only ofw_bus_gen_*(), it might be worth garbage-collecting the other
methods as well.

443c3d0bd1 Do not place the sglist used for Rx/Tx on the stack
The sglist segment array has grown to a bit over 512 bytes (on
64-bit system) which is more than ideally should be put on the
stack. Instead allocate an appropriately sized sglist and hang
it off each Rx/Tx queue structure.

Bump the maximum number of Tx segments to 64 to make it unlikely
we'll have defragment an mbuf chain. Our previous count was
rounded up to this value since it is the next power of two, so
effective memory usage should not change.

Also only allocate the maximum number of Tx segments if TSO was
negotiated.

06763f5e55 Provide a simpler and more standards-compliant simplebus implementation to

does not implement some BERI-specific features (which hopefully won't be

priority when built, until MIPS interrupt domain support is rearranged.

bbc6da03ef Open Firmware interrupt specifiers can consist of arbitrary-length byte
strings and include arbitrary information (IRQ line/domain/sense). When the
ofw_bus_map_intr() API was introduced, it assumed that, as on most systems,
these were either 1 cell, containing an interrupt line, or 2, containing
a line number plus a sense code. It turns out a non-negligible number of
ARM systems use 3 (or even 4!) cells for interrupts, so make this more
general.

7e3343bfcf Some BIOSes incorrectly use standard memory resource ranges to list
the memory ranges that they decode for downstream devices rather than
creating ResourceProducer range resource entries.  The result is that
we allocate the full range to the PCI root bridge device causing
allocations in child devices to all fail.

As a workaround, ignore any standard memory resources on a PCI root
bridge device.  It is normal for a PCI root bridge to allocate an I/O
resource for the I/O ports used for PCI config access, but I have not
seen any PCI root bridges that legitimately allocate a memory resource.

23c628f7f7 Remove not applicable PI_SDTR_ABLE and PI_WIDE_16 hba_inquiry flags to
make CAM to not try negotiate unsupported settings and suppress warnings.

While there, enable command queuing on pass-through devices, announced
in hba_inquiry, but disabled.  Even though queue size is very small, It
seems working well enough.

5945b5f5ab Rename definition of IEEE80211_FC1_WEP to IEEE80211_FC1_PROTECTED.
The origin of WEP comes from IEEE Std 802.11-1997 where it defines
whether the frame body of MAC frame has been encrypted using WEP
algorithm or not.
IEEE Std. 802.11-2007 changes WEP to Protected Frame, indicates
whether the frame is protected by a cryptographic encapsulation
algorithm.
