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.

machine, for which 32bit compatibilty code has been added.
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
purpose.
From one dev node i.e mrgaraid_sa_ioctl_node we have to find out the
controller instance in case of multicontroller, for which one management info

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
u3g.c and are the same as the E3131. However, the R215/E5372 is an NCM

may be needed to better identify the other device IDs.
