From 58ab4881de0966ab351fc2d423fd98cfb3c0332f Mon Sep 17 00:00:00 2001 From: Dengdui Huang Date: Thu, 7 Nov 2024 19:56:45 +0800 Subject: [PATCH] net/hns3: fix fully use hardware flow director table [ upstream commit b8e60c33168a2999604c17322dd0198a6746428f ] The hns3 driver checks whether the flow rule is repeatedly inserted based on rte_hash. Currently, the rte_hash extendable bucket table feature is not enabled. When there are many hash conflicts, the hash table space cannot be fully used. So the flow rule maybe cannot be inserted even if the hardware flow director table there are still free. This patch fix it by enabling the rte_hash extensible bucket table feature.
