From: Subbaraya Sundeep <sbhatta@xxxxxxxxxxx>
commit 59e1be6f83b928a04189bbf3ab683a1fc6248db3 upstream.
Check the mask for non-zero value before installing tc filters
for L4 source and destination ports. Otherwise installing a
filter for source port installs destination port too and
vice-versa.
Fixes: 1d4d9e42c240 ("octeontx2-pf: Add tc flower hardware offload on ingress traffic")
