1. While disabling interrupt the FW disables interrupts for only 16 vectors.
In case of Invader which supports 96 MSI-x vectors, some spurious interrupts
may come on other vectors even after interrupt disable. So, driver uses a flag
and ignores the spurious interrupts.
2. Reply queue depth is made double the number of commands supported by FW.
3. Misplaced interrupt enable code is now moved down in the OCR path.
4. Updated error handling code in OCR path.
5. Removed un-necessary print.

There will be a small window where IO will come from OS with old RAID map.
This patch will update adapter state to MEGASAS_HBA_OPERATIONAL,
only after driver has new RAID map to avoid any IOs getting build using old RAID map.

initialize the MFUNC registers. Our old test of assuming that if this
register is set at all is not quite right. Many scenarios (including
the power-on defaults for chips w/o EEPROMs) land us in trouble. The
MFUNC0 pin should be set to signal #INTA and the MFUNC1 pin should be
set to signal #INTB of multi-socketed devices. Since my memory recalls
issues with blindly clearing the upper bytes of this register, perform
the heuristic only when both MFUNC0 and 1 are clear. We won't work
well using these pins for GPIO, and the serial interrupts won't save
us because we go out of our way to generally disable them. They are
needed to support legacy drivers for 16-bit PC Cards that are
hard-wired to specific IRQ values. Since FreeBSD never had any of
these, we configure the more reliable direct signaling. This was just
one small piece of that which had been left out back in the day.
Summary:
This has been tested on the RB800, but should work on the RB333, RB600, and
RB1100 as well.
It's currently missing ECC support, but read and write are complete.

interface without breaking ABI or API compatibility with existing drivers.
The existing data structures used to communicate between the kernel and
driver portions of PPS processing contain no spare/padding fields and no
flags field or other straightforward mechanism for communicating changes
in the structures or behaviors of the code. This makes it difficult to
MFC new features added to the PPS facility. ABI compatibility is
important; out-of-tree drivers in module form are known to exist. (Note
that the existing api_version field in the pps_params structure must
contain the value mandated by RFC 2783 and any RFCs that come along after.)
These changes introduce a pair of abi-version fields which are filled in
by the driver and the kernel respectively to indicate the interface
version. The driver sets its version field before calling the new
pps_init_abi() function. That lets the kernel know how much of the
pps_state structure is understood by the driver and it can avoid using
newer fields at the end of the structure that it knows about if the driver
is a lower version. The kernel fills in its version field during the init
call, letting the driver know what features and data the kernel supports.
To implement the new version information in a way that is backwards
compatible with code from before these changes, the high bit of the
lightly-used 'kcmode' field is repurposed as a flag bit that indicates the
driver is aware of the abi versioning scheme. Basically if this bit is
clear that indicates a "version 0" driver and if it is set the driver_abi
field indicates the version.
These changes also move the recently-added 'mtx' field of pps_state from
the middle to the end of the structure, and make the kernel code that uses
this field conditional on the driver being abi version 1 or higher. It
changes the only driver currently supplying the mtx field, usb_serial, to
use pps_init_abi().

Change the nvlist_recv() function to take additional argument that
specifies flags expected on the received nvlist. Receiving a nvlist with
different set of flags than the ones we expect might lead to undefined
behaviour, which might be potentially dangerous.
