Subject: net/hns3: allow adding queue buffer size hash rule
|
|
|
|
[ upstream commit 8095bf3e6d8ca7349e0a15f95407acd2063e7be0 ]
|
|
|
|
The maximum queue number from RSS flow rule allowed depends on
|
|
the maximum queue number (512) under one TC instead of the one
|
|
of Rx/Tx queue so as to eliminate restrictions on user usage.
|
|
