patch 'common/cnxk: fix DPI memzone name' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=ab0aa8b245c03765d48ddb3fa569850a0cf66816

Thanks.

Subject: [PATCH] common/cnxk: fix DPI memzone name
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 7ca20b053cb739d021d2ff33a5ba75651048c322 ]

roc_dpi was using vfid as part of name for memzone allocation.
This led to memzone allocation failure in case of multiple
physical functions. vfid is not unique by itself since multiple
physical functions can have the same virtual function indices.
So use complete DBDF as part of memzone name to make it unique.

Fixes: b6e395692b6d ("common/cnxk: add DPI DMA support")
