This flag denotes local attachment of the phy. There are two problems
with it:
1) It's actually redundant ... you can get the same information simply
by seeing whether a host is the phys parent
2) we condition a lot of phy parameters on it on the false assumption
that we can only control local phys. I'm wiring up phy resets in the
aic94xx now, and it will be able to reset non-local phys as well.
I fixed 2) by moving the local check into the reset and stats function
of the mptsas, since that seems to be the only HBA that can't
(currently) control non-local phys.

This patch corrects a problem in mptfc which can result in targets
being removed after executing an "lsiutil 99" reset of the fibre
channel ports.
The last rescan event was being processed before the setup reset work
due to an inappropriate optimization in the event processing logic.
Every rescan event is now queued for execution and the setup reset
work now executes in the proper sequence.

Based upon a conversation I had with LSI's fibre channel firmware guru,
this patch adds another condition under which the driver waits for the
firmware link initialization / target discovery to complete.

This takes advantage of the sas class backlink function to show which
port on an expander is used to communicate with the parent.

Fix's to insure download boot could occur when
either channel of 1030 is reset. Necessary in order
for onboard controller in flashless environment
to become operational.

Fix's to insure proper status is returned to midlayer

Also sanity checks to prevent scsi cmd from being
double completed during error recovery.

Using the port_id for the channel is completely unnecessary since the
host_id/target_id are constructed to be globally unique. Also move
the mptsas driver on to virtual channel 1 for its raid devices.

This allows us to be rid of the machinery in mptsas for creating and
tracking port numbers. Since mptsas is merely inventing the numbers,
the SAS transport class may as well do it instead.

One of the current problems the mptsas driver has is that of "ghost"
devices (these are devices the firmware reports as existing, but what
they actually represent are the parents of a lower device), so for
example in my dual expander configuration, three expanders actually show
up, two for the real expanders but a third is created because the
firmware reports that the lower expander also has another expander
connected (which is simply the port going back to the upper expander).
The attached patch eliminates all these ghosts by not allocating any
devices for them if the SAS address is the SAS address of the parent.

The way mpt_interrupt() was coded, it was impossible for the unhandled
interrupt detection logic to ever trigger. All interrupt handlers should
return IRQ_NONE when they have nothing to do.
