Subject: [dpdk-dev] [PATCH v2 1/2] net/ice: remove support for IP fragment default RSS
Date: Thu, 16 Sep 2021 13:03:51 +0800	[thread overview]
Message-ID: <20210916050351.493484-1-wenjun1.wu@intel.com> (raw)
In-Reply-To: <20210916045523.492944-1-wenjun1.wu@intel.com>

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.
