Change the threshold number of descriptors used to trigger CMB writes.
The vendor reports that under certain conditions this will reduce the
number of unnecessary tx interrupts and improve rx performance.
This change is lifted directly from vendor version 1.2.40.2 of the L1
driver.

Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown
in dmesg. This meant restarting rx DMA had been rejected by the hypervisor.
This issue would caused if the guest os requested starting DMA when
the hypervisor thought the DMA was in progress.
The state machine for DMA status of the hypervisor would be updated
by processing interrupt in the hypervisor.
Thus we should wait for the interrupt delivery before restarting
DMA.

gelic: TX descriptor handling cleanup
- Emitted return value of NETDEV_TX_LOCKED when DMA map or kick
failure.
Now it would free the skb, update drop packet statistics
and return OK. Requested from Jeff Garzik.
- Enable tx queue if number of free descriptors are more than 2
- Fixed descriptor leak if dma map for second descriptor failed
- Stopped calling xmit handler from interrupt handler in order
to recheck tx queue. Instead, call appropriate helper functions.

The firmware should be loaded after resetting hardware during PCI probe,
besides module unload. This fixes issue with 2nd port of multiport adapter
on powerpc blades. This patch also fixes a bug that PCI resources are not
freed if dma watchdog shutdown failed. The dma watchdog poll messages
during module unload are also suppressed.

The recent 9p commit: bd238fb431f31989898423c8b6496bc8c4204a86 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.
And since it was only for debugging clearly did not need a binary fast
path in any case. So this patch just remove the binary numbers.
See Documentation/sysctl/ctl_unnumbered.txt for more details.
While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.

eHCA2 supports QP queues that can be as small as 512 bytes. This
greatly reduces memory overhead for consumers that use lots of QPs
with small queues (e.g. RDMA-only QPs). Apart from dealing with
firmware, this code needs to manage bite-sized chunks of kernel pages,
making sure that no kernel page is shared between different protection
domains.

Add support for MR pages larger than 4K on eHCA2. This reduces
firmware memory consumption. If enabled via the mr_largepage module
parameter, the MR page size will be determined based on the MR length
and the hardware capabilities -- if the MR is >= 16M, 16M pages are
used, for example.

The error handling code at err_wrid in create_qp_common() does not
handle a userspace QP attached to an SRQ correctly, since it ends up
in the else clause of the if statement. This means it tries to
kfree() the uninitialized qp->sq.wrid and qp->rq.wrid pointers. Fix
this so we only free the wrid arrays for kernel QPs.

The FW command token is currently only updated on a command completion
event. This means that on command timeout, the same token will be
reused for new command, which results in a mess if the timed out
command *does* eventually complete.
This is the same change as the patch for mthca from Michael
S. Tsirkin <mst@dev.mellanox.co.il> that was just merged. It seems
sensible to avoid gratuitous differences in FW command processing
between mthca and mlx4.

The ipath_layer.[ch] code was an attempt to provide a single interface
for the ipath verbs and ipath_ether code to use. As verbs
functionality increased, the layer's functionality became insufficient
and the verbs code broke away to interface directly to the driver.
The failed attempt to get ipath_ether upstream was the final nail in
the coffin and now it sits quietly in a dark kernel.org corner waiting
for someone to notice the smell and send it along to it's final
resting place. Roland Dreier was that someone -- this patch expands
on his work...

Currently, bsg doesn't make class backlinks (a process whereby you'd get
a link to bsg in the device directory in the same way you get one for
sg). This is because the bsg device is uninitialised, so the class
device has nothing it can attach to. The fix is to make the bsg device
point to the cdevice of the entity creating the bsg, necessitating
changing the bsg_register_queue() prototype into a form that takes the
generic device.

unfortunately, if IS_ERR(class_dev) is true, that means class_dev isn't
null and the check in the error leg is pointless ... it's also asking
for trouble to request unregistration of a device we haven't actually
created (although it works currently). Fix by using explicit gotos and
unregisters.

There's currently no destructor for the bsg components. If you insert

destruction.
