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.
|
||
|
|
