[SCSI] storvsc: Increase the value of scsi timeout for storvsc devices
The standard scsi timeout is not appropriate in some of the environments where
Hyper-V is deployed. Set this timeout appropriately for all devices managed
by this driver.
On cloud environments where storage latencies may be unbounded, having the
scsi layer initiating recovery can be problematic since (a) the host is
already implementing a variety of recovery strategies and (b) implementing a
recovery strategy at the VM level may be more appropriate in cases where
storage latencies exceed a certain threshold.

One of the customer had reported that the set of raid logical arrays will
become unavailable (I/O offline) after a long hours of IO stress test. The OS
wouldn`t be accessible afterwards and require a hard reset.
This driver patch has a fix for race condition between the doorbell and the
circular buffer. The driver is modified to do an extra read after clearing the
doorbell in case there had been a completion posted during the small timing
window.
With this fix, we ran IO stress for ~13 days. There were no IO failures.

SATA drives located behind a SAS controller would incorrectly receive
WRITE SAME commands. Tweak the heuristics so that:
- If REPORT SUPPORTED OPERATION CODES is provided we will use that to
choose between WRITE SAME(16), WRITE SAME(10) and disabled. This also
fixes an issue with the old code which would issue WRITE SAME(10)
despite the command not being whitelisted in REPORT SUPPORTED
OPERATION CODES.
- If REPORT SUPPORTED OPERATION CODES is not provided we will fall back
to WRITE SAME(10) unless the device has an ATA Information VPD page.
The assumption is that a SATL which is smart enough to implement
WRITE SAME would also provide REPORT SUPPORTED OPERATION CODES.
To facilitate the new heuristics scsi_report_opcode() has been modified
to so we can distinguish between "operation not supported" and "RSOC not
supported".

fcoe: Use correct API to set vlan tag for FCoE Ethertype skbs
fcoe_xmit was coded such that it would skip the vlan net device/layer
and instead set some vlan flags and transmit on the real net device.
The real net device has code that would add the vlan tag for fcoe skbs.
This avoids some extra processing for data frames and provides a small
performance improvement.
Since fcoe_xmit was not using the vlan net device, __vlan_put_tag
within the real net device's xmit routine was ultimately being
called to set the vlan tag.
With the below change the behavior of __vlan_put_tag changed slightly,
it now sets the skb->protocol = vlan_proto. vlan_proto was not a field
being set by fcoe_xmit, so the skb->protocol is now not being set to
ETH_P_8021Q, as it should be.
This patch converts fcoe_xmit to use the vlan_put_tag routine which
will tag the skb and fcoe will continue to transmit fcoe skbs on the
real net device.
For reference, the below change was the one that altered the
__vlan_put_tag behavior.
net: vlan: add protocol argument to packet tagging functions
Add a protocol argument to the VLAN packet tagging functions. In case of HW
tagging, we need that protocol available in the ndo_start_xmit functions,
so it is stored in a new field in the skb. The new field fits into a hole
(on 64 bit) and doesn't increase the sks's size.

[SCSI] megaraid_sas: Add support for Uneven Span PRL11
MegaRAID older Firmware does not support uneven span configuration for PRL11.
E.g User wants to create 34 Driver PRL11 config, it was not possible using old
firmware, since it was not supported configuration in old firmware
Old Firmware expect even number of Drives in each span and same number of
physical drives at each span. Considering above design, 17 Drives at Span-0
and 17 drives at span-1 was not possible.
Now, using this new feature Firmware and Driver both required changes. New
Firmware can allow user to create 16 Drives at span-0 and 18 Drives at
span-1. This will allow user to create 34 Drives Uneven span PRL11.
RAID map is interface between Driver and FW to fetch all required
fields(attributes) for each Virtual Drives. Since legacy RAID map consider
Even Span design, there was no place to keep Uneven span information in
existing Raid map. Because of this limitation, for Uneven span VD, driver can
not use RAID map.
This patch address the changes required in Driver to support Uneven span PRL11
support.
1. Driver will find if Firmware has UnevenSpanSupport or not by reading
Controller Info.
2. If Firmware has UnvenSpan PRL11 support, then Driver will inform about its
capability of handling UnevenSpan PRL11 to the firmware.
3. Driver will update its copy of span info on each time Raid map update is
called.
4. Follow different IO path if it is Uneven Span. (For Uneven Span, Driver
uses Span Set info to find relavent fields for that particular Virtual
Disk)
More verbose prints will be available by setting "SPAN_DEBUG" to 1 at
compilation time.
