Fixes tag: Fixes: 81a43620("octeontx2-pf: Add RSS multi group support")
Has these problem(s):
	- missing space between the SHA1 and the subject
	- SHA1 should be at least 12 digits long
	  Can be fixed by setting core.abbrev to 12 (or more) or (for git v2.11
	  or later) just making sure it is not set (or set to "auto").

Please fix the entire submission.
