Subject: [PATCH v3 3/3] net/mlx5: implement VXLAN last reserved modification
Date: Tue, 4 Jun 2024 15:15:02 +0300 [thread overview]
Message-ID: <20240604121502.376102-4-rongweil@nvidia.com> (raw)
In-Reply-To: <20240604121502.376102-1-rongweil@nvidia.com>
Implementing the VxLAN last reserved byte modification.
Following the RFC, the field is only 1 byte and needs to
use the field_length as 8 instead of the real dst_field->size.
