Subject: [dpdk-dev] [PATCH v2] net/ice: remove redundant RSS configuration for GTPU
Date: Sat,  8 May 2021 16:40:41 +0800	[thread overview]
Message-ID: <20210508084041.306170-1-wenjun1.wu@intel.com> (raw)
In-Reply-To: <20210506022023.1292424-1-wenjun1.wu@intel.com>

Originally, the default RSS for GTPU is inner fields. Now, we hope outer
RSS for GTPU to be the default.

Since RSS for ipv4, RSS for ipv6, RSS for UDP and RSS for TCP can cover
the cases of outer RSS for GTPU, this patch deletes redundant default
RSS configurations for GTPU.

Signed-off-by: Wenjun Wu <wenjun1.wu@intel.com>
---
v2: GTPU and PPPoE share the value of cfg.hash_flds, patch v1 delete
the assignment of cfg.hash_flds, which lead to RSS for PPPoE unable to
work. Patch v2 adds these assignment statements.
