Added new callbacks phy_enable and set_phy_speed in the
mpt2sas_transport_functions template. This will allow end user to

Current implementation only supports direct attached phys, but we
could in the future add support for expander based phys.
A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added;
this wrapper function used to send request to controller firmware to modify
the phys and link rates. A new subroutine _transport_find_local_phy was added;
a function for easly obtaining the local phy object for direct attached.
Example to disable a phy
echo 0 > /sys/class/phy3:0/enable
Example to enable the same phy
echo 1 > /sys/class/phy3:0/enable
Example to change the link rate to 1.5

[SCSI] lpfc: restore MSI-X/MSI support
A Gentoo bug report [1] showed that as of 2.6.31 lpfc only uses INTx interrupts.
This patch restores lpfc's ability to support MSI-X/MSI interrupts that the
"Addition of SLI4 Interface - Base Support" patch [2] broke.
It reestablishes MSI-X as the default interrupt method and in case MSI-X is not
supported lpfc_sli{4,}_enable_intr fallbacks to MSI and then to INTx.
[1]: http://bugs.gentoo.org/show_bug.cgi?id=296319

da0436e915a5c17ee79e72c1bf978a4ebb1cbf4d
[James Smart:
Background:
Nothing Broke. This was intended.
We had originally enabled MSI-X by default, but in qualification within the
last 12 months, we encountered a major catch-22:
There were at least 4 platforms, from 2 major OEMs, that :
- Say they support MSI-X - platform routines work and act as if they do.
- We enable it, generate a test interrupt to check they really do deliver it,
and it works.
- But shortly after attachment, the system hangs or loses interrupts,
resulting in a bad system behavior.
Given the distro's picking up the 2.6.32 kernel, we had to stick with a
default of MSI-X off, with user-enabled MSI-X as these platforms couldn't get
fixed.
However, we're also now encountering platforms that require MSI-X and never
INTx, so we must change. It's desired also for also for performance reasons.
So - now (2.6.33) is the right time to re-enable MSI-X by default.

This failure happens when esp_reconnect_with_tag() tries to read in two

[SCSI] scsi_transport_fc: Remove capping from dev_loss_tmo
Currently dev_loss_tmo is capped by SCSI_DEVICE_BLOCK_MAX_TIMEOUT.
This causes problem with multipathing when the 'no_path_retry' setting
exceeds the dev_loss_tmo setting, as then the system might run into
a deadlock when all paths have been removed temporarily for longer
than dev_loss_tmo.
The principal reasons for the capping has been that we should
not allow a remote port to remain in status 'blocked' indefinitely,
so the capping is there to ensure that the port status is being reset
eventually.
However, the fast_io_fail_tmo will also move the remote port out of
the 'blocked' state, so for any HBA driver implementing both the
capping should really be on the fast_io_fail_tmo, and not on the
dev_loss_tmo.
This patch implements just that, ie the fast_io_fail_tmo is capped
to SCSI_DEVICE_BLOCK_TIMEOUT and the capping is removed from
dev_loss_tmo when fast_io_fail_tmo is set.
This allows us to synchronize the dev_loss_tmo setting to the
'no_path_retry' setting from multipathing thus avoiding the deadlock.

[SCSI] scsi_transport_fc: Allow LLD to reset FC BSG timeout
The hardware used with zfcp cannot abort a currently pending CT or ELS
request. Therefore we need the option to postpone the timeout
triggered request abort within the fc layer, since there is nothing
zfcp can do to stop the request at this point.
