Currently, the driver plays off the fact that older sli4 adapters have a

requires us to wait for a later mailbox completion. This changes the put

lpfc: Fix host reset escalation killing all IOs.
Fix host reset escalation killing all IOs.
SLI-3 adapters will use a new host template. The template differs
from SLI-4 adapters in that it does not have an eh_host_reset_handler.
Lpfc has traditionally never had a host_reset. The host reset
handler was added when we ran into a stuck hardware condition on a
SLI-4 adapter. The host_reset will reset and reinit the pci function,
clearing the hardware condition.
Unfortunately, the host reset handler uses attach/detach code paths,
which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a
host_reset will completely remove the scsi_host from the system. As a
new call to scsi_add_host() is made, the shost# changes, which results
in completely new scsi_devices and device names. All the older scsi
devices on the old shost# are now orphaned and unrecoverable.
We realize we need to re-implement the host_reset_handler so the scsi_host
stays registered across the host_reset, but that will be a rather
lengthy effort. In the short term, we had an immediate need to restore
the SLI-3 devices to their working behavior, with the easiest path being
to remove their host_reset handler.

ipr: Reboot speed improvements
Currently when performing a reboot with an ipr adapter,
the adapter gets shutdown completely, flushing all write
cache, as well as performing a full hardware reset of the card
during the shutdown phase of the old kernel. This ensures
the adapter is in a fully quiesced state across the reboot.
There are scenarios, however, such as when performing
kexec, where this full adapter shutdown is not required
and not desired, since it can make the reboot process take
noticeably longer.
This patch adds a module parameter to allow for skipping the
full shutdown during reboot. Rather than performing a full
adapter shutdown and reset, we simply cancel any outstanding
error buffers, place the adapter into a state where it has no
memory of any DMA addresses from the old kernel, then disable
the device. This significantly speeds up kexec boot, particularly
in configurations with multiple ipr adapters.
