-Subject: [PATCH] net: ethernet: mtk_eth_soc: avoid creating duplicate offload
- entries
-
-Sometimes multiple CLS_REPLACE calls are issued for the same connection.
-rhashtable_insert_fast does not check for these duplicates, so multiple
-hardware flow entries can be created.
-Fix this by checking for an existing entry early
