Subject: [dpdk-dev] [PATCH v1 1/2] net/ice: remove support for IP fragment default RSS
Date: Thu, 16 Sep 2021 12:55:23 +0800	[thread overview]
Message-ID: <20210916045523.492944-1-wenjun1.wu@intel.com> (raw)

To support independent IP fragment default RSS, considerable additional work
need to be done, so we decide to remove this feature to avoid some unexpected
behavior we have observed, meanwhile user always can use rte_flow to create
RSS for IP fragment packet explicitly.
