scsi: remove eh_timed_out methods in the transport template
Instead define the timeout behavior purely based on the host_template
eh_timed_out method and wire up the existing transport implementations
in the host templates. This also clears up the confusion that the
transport template method overrides the host template one, so some
drivers have to re-override the transport template one.

The v2 SAS controller needs more time to detect channel idle

When processing an AFU asynchronous interrupt, if the action results in an

scsi: megaraid_sas: SAS3.5 Generic Megaraid Controllers Fast Path for RAID 1/10 Writes
To improve RAID 1/10 Write performance, OS drivers need to issue the
required Write IOs as Fast Path IOs (after the appropriate checks
allowing Fast Path to be used) to the appropriate physical drives
(translated from the OS logical IO) and wait for all Write IOs to complete.
Design: A write IO on RAID volume will be examined if it can be sent in
Fast Path based on IO size and starting LBA and ending LBA falling on to
a Physical Drive boundary. If the underlying RAID volume is a RAID 1/10,
driver issues two fast path write IOs one for each corresponding physical
drive after computing the corresponding start LBA for each physical drive.
Both write IOs will have the same payload and are posted to HW such that
replies land in the same reply queue.
If there are no resources available for sending two IOs, driver will send
the original IO from SCSI layer to RAID volume through the Firmware.
Based on PCI bandwidth and write payload, every second this feature is
enabled/disabled.
When both IOs are completed by HW, the resources will be released
and SCSI IO completion handler will be called.

There is a bug in the current driver in that certain hisi_hba and port

Currently the all the slot processing for the completion queue is done

of the DME local/peer attributes access before setting the "hba->pwr_info"
to default power mode. If we are doing link startup as part of error
recovery then old power mode might be set to FAST mode and doing DME peer
access (after link startup but before updating "hba->pwr_info" to default
power mode) unintentionally tries to switch from FAST to FAST_AUTO mode (if

Above issue is fixed by setting the default power mode immediately after
