Subject: net/mlx5: Bridge, provide flow source hints
Patch-mainline: v5.16-rc1
Git-commit: 17ac528d886841a0b183f4d4a0205176eccfd158
References: jsc#SLE-19253

Currently, SMFS mode doesn't support rx-loopback flows which causes bridge
egress rules to be rejected because without hint rules for both rx and tx
destinations are created by default. Provide explicit flow source hints for
compatibility with SMFS.
