[ Upstream commit 53bb66983f34d4ff0af179fe228e2c55e1e45921 ]
The vf_id variable is dealt with in the code in inconsistent ways of sign usage, preventing compilation with -Werror=sign-compare. Fix this problem in the code by always treating vf_id as unsigned, since there are no valid values of vf_id that are negative.
