[dpdk-dev] [PATCH 1/2] examples: strip directory and use suffix as name

[dpdk-dev] [PATCH 1/2] examples: strip directory and use suffix as name

[Ali Alnubani]

This would allow correctly naming an application residing
in a subdirectory. For example, if the example is set to 'path/to/app',
then the name would be 'app'.
This doesn't affect the naming of an example that isn't in a subdirectory.

Since these are in alphabetical order, I think we should keep the
multi-process apps in the list in the correct order, rather than at the end.

I believe your previous patch in this set already set up the names
correctly for these apps, so I think you should remove this and the other
name assignment lines in the other files. I'd like to try and enforce
consistency in naming, and not having overrides of the name value in the
individual app meson.build files is key to enforcing that consistency.

Otherwise, thanks for doing this, and the rest of the patch looks fine to
me.

I left those assignments from a previous version of the patchset, my bad.
