Commit Message

Ergin, Mesut A July 25, 2019, 9:50 p.m. UTC 
  This commit fixes an issue with the error checking in flow
MARK action. Previously, (ANY + MARK) would fail, as the
(mark_spec == 0) condition would cause an early error return,
however really it is (mark_spec != 0) that should cause the
early error return.

Flipping the binary comparison corrects the behaviour, and
(ANY + MARK) now succeeds, while (MARK + MARK) fails.

Fixes: 0bbcfc706a2b ("net/i40e: support MARK and RSS flow action")
