Subject: [PATCH 0/4] Remove SSE from some Intel drivers
Date: Mon, 25 Aug 2025 12:35:44 +0000	[thread overview]
Message-ID: <20250825123548.1177090-1-ciara.loftus@intel.com> (raw)

This patch removes the SSE Rx and Tx paths from the i40e, iavf and ice
driverss. Each of these drivers have faster vector paths (AVX2 and AVX-512)
which have feature parity with the SSE paths. In environments where AVX2 or
AVX-512 are not supported, the scalar path will still be used, which also
has feature parity.

This series is intended for the next-net-intel tree.

Ciara Loftus (4):
  net/i40e: remove SSE vector path
  net/iavf: remove SSE vector path
  net/ice: remove SSE vector path
  doc: add release note entry for SSE removal
