[Bug 1899802] Re: [Ubuntu 21.04 FEAT] mpt3sas: Request to include the patch set which supports topology where zoning is enabled in expander

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
focal' to 'verification-done-focal'. If the problem still exists, change
the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
Request to include patch set "PATCH 00/14] mpt3sas: Add support for
multi-port path topology" which will support the topologies where
zoning is enabled in the expander as shown below,

Zone 1 Zone 2
|-----------------| |----------------|
| HD1 ..... HD25 | | HD26 ......HD50|
| |==================================| |

| | Expander | |

|-----------|-----| |----|-----------|

Current driver doesn't support this type of topology and will add only one zoned drives to the OS. So to support these types of topology we need below patch set in the driver.

So, requesting you include this patch for next upcoming Ubuntu kernel
release.

Currently we have posted this patch set to upstream community and they
yet to review this patch set. Meanwhile If I get the base kernel
source code for next upcoming Ubuntu kernel then I can prepare the
patches over this base kernel source and share it in this BZ.

Thanks,
Sreekanth
