There's a very remote, but possible, chance that the integer part read will
fail, but the fraction read succeeds, at which point the reported temperature is
invalid.

- Add a mutex to protect the softc.
- Use callout(9) instead of timeout(9).
- Consolidate duplicated detach routines into a bus-independent detach
routine.
- Add an extra sleep lock flag (MSESC_READING) to prevent other readers
from reading while the first reader is copying data out of sc_bytes[]
via uiomove().
- Use bus_*() instead of bus_space_*().

- Read the counts of received, dropped, and transmitted management
packets and add sysctl nodes for them.
- Fix the total octets received/transmitted to read all 64 bits of
the counters.
- Add missing sysctl nodes for rlec, tncrs, fcruc, tor, and tot.
- Remove spurious spaces.

It allows to push out some final data from the send queue to the socket
before its close. In particular, it increases chances for logout response
to be delivered to the initiator.
* Add a bus_if.m method - get_domain() - returning the VM domain or
ENOENT if the device isn't in a VM domain;
* Add bus methods to print out the domain of the device if appropriate;
* Add code in srat.c to save the PXM -> VM domain mapping that's done and
expose a function to translate VM domain -> PXM;
* Add ACPI and ACPI PCI methods to check if the bus has a _PXM attribute
and if so map it to the VM domain;
* (.. yes, this works recursively.)
* Have the pci bus glue print out the device VM domain if present.
Note: this is just the plumbing to start enumerating information -
it doesn't at all modify behaviour.

where as there are limited number(32) of mfi commands in the pool.
The mfi command pool is now restricted to 27 simultaneous accesses by using
a counting semaphore while calling the passthru function.
In the mrsas_cam.c source file there was a same function name mrsas_poll(),
which was same as the mrsas_poll() implemented in the mrsas.c file for the
polling interface.
To clearly distinguish the functionality by usage we have renamed the former
as mrsas_cam_poll().
In the passthru function let's say it has got an mfi command from the pool
but it has failed in one of the DMA function call which will lead to leak
an mfi command because in the ERROR case it directly returns and not freeing up
the occupied mfi command.

As in linux there is only one device entry that is used to fire IOCTL commands,
a new device entry megaraid_sas_ioctl_node is added for solely this

From one dev node i.e mrgaraid_sa_ioctl_node we have to find out the

E.g: If the user wants to create more than 64VD on a controller,
it is not possible on current firmware/driver.
New feature and requirement to support upto 256VD, firmware/driver/apps need changes.
In addition to that, there must be a backward compatibility of the new driver with the
older firmware and vice versa.
RAID map is the interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives.
In the earlier design driver was using the FW copy of RAID map where as
in the new design the Driver will keep the RAID map copy of its own; on which
it will operate for any raid map access in fast path.
Local driver raid map copy will provide ease of access through out the code
and provide generic interface for future FW raid map changes.
For the backward compatibility driver will notify FW that it supports 256VD
to the FW in driver capability field.
Based on the controller properly returned by the FW, the Driver will know
whether it supports 256VD or not and will copy the RAID map accordingly.
At any given time, driver will always have old or new Raid map.

These controllers seem to have the same feature of AR813x/AR815x and
improved RSS support(4 TX queues and 8 RX queues). alc(4) supports
all hardware features except RSS. I didn't implement RX checksum
offloading for AR816x/AR817x just because I couldn't get
confirmation from the Vendor whether AR816x/AR817x corrected its
predecessor's RX checksum offloading bug on fragmented packets.
This change adds supports for the following controllers.
o AR8161 PCIe Gigabit Ethernet controller
o AR8162 PCIe Fast Ethernet controller
o AR8171 PCIe Gigabit Ethernet controller
o AR8172 PCIe Fast Ethernet controller
o Killer E2200 Gigabit Ethernet controller

Interestingly, the standard E5372 IDs (12d1:1506) are currently listed in

It was found that VirtualBox' AHCI does not allow nterrupt to be cleared
before the interrupt status register is read, causing interrupt storm.
AHCI specification allows to skip this register use when multi-vector MSI
is enabled and so interrupting port is known. For single-vector MSI that
is not stated explicitly, but if the port is only one, it is obviously
known too.
When the screen size is unknown, it's set to 0x0. We can't use that as
the buffer size, otherwise, functions such as vtbuf_fill() will fail.
This fixes a panic on RaspberryPi, where there's no vt(4) backend
configured early in boot.

Add new functions to manipulate these mode & state, instead of calling
kbdd_ioctl() everyhere.
This fixes at least two bugs:
1. The state of the Scroll Lock LED and the state of scroll mode
could be out-of-sync. For instance, if one enables scroll mode on
window #1 and switches to window #2, the LED would remain on, but
the window wouldn't be in scroll mode.
Similarily, when switching between a console and an X.Org
session, the LED states could be inconsistent with the real
state.
2. When exiting from an X.Org session, the user could be unable to
type anything. The workaround was to switch to another console
window and come back.
