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
|
|
|
|
Fixes: 502e84e2382d ("net: ethernet: mtk_eth_soc: add flow offloading support")
