[dpdk-dev] [PATCH] app/testpmd: fix pf/vf check of flow director

[Wenzhuo Lu]

Parameters pf & vf are added into most of flow director
filter CLIs.
But mac-valn and tunnel filters don't have these parameters,
the parameters should not be checked for mac-vlan and tunnel
filters.

Check-git-log script throws a couple of errors:

Wrong headline lowercase:
        app/testpmd: fix pf/vf check of flow director -> PF/VF
Missing blank line after 'Fixes' tag:
        Fixes: e6a68c013353 ("app/testpmd: extend commands for flow director in VF")

This bug was reported and fixed by Frederico Cadete:
	http://dpdk.org/patch/15264
We have waited long to have a review saying it requires
an optional parameter in the command line.
And finally you re-post a fixed version of the same approach
without any comment to the original thread or a reference here.
Please be more careful with occasional contributors.
