Subject: [RFC PATCH 18/21] net/ice: use vector SW ring for all vector paths
Date: Fri, 22 Nov 2024 12:54:11 +0000 [thread overview]
Message-ID: <20241122125418.2857301-19-bruce.richardson@intel.com> (raw)
In-Reply-To: <20241122125418.2857301-1-bruce.richardson@intel.com>
The AVX-512 code path used a smaller SW ring structure only containing
the mbuf pointer, but no other fields. The other fields are only used in
the scalar code path, so update all vector driver code paths to use the
smaller, faster structure.
