This offload allows to free the mbufs on\ntransmit completion in the most efficient way. It requires\nthe all mbufs were allocated from the same pool, have\nthe reference counter value as 1, and have no any externally\nattached buffers.\n\nThe patchset is split in two parts, the first one is overall\nsend loop optimization and can be ported back to stable release,\nand also is the preparation step before introducing the fast\nfree offload. The second part provides the code for the feature.\n\nSigned-off-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com>\n\n---\nv1: http://patches.dpdk.org/patch/85482/\nv2: release notes, PMD features and documentation update\nv3: typo fixes, documentation update\n\nViacheslav Ovsiienko (2):\n net/mlx5: optimize inline mbuf freeing\n net/mlx5: add mbuf fast free offload support\n\n doc/guides/nics/features/mlx5.ini | 1 +\n doc/guides/nics/mlx5.rst | 12 ++++++\n doc/guides/rel_notes/release_21_02.rst | 2 +-\n drivers/net/mlx5/mlx5_rxtx.c | 67 +++++++++++++++++++++++++++++-----\n drivers/net/mlx5/mlx5_rxtx.h | 2 +\n drivers/net/mlx5/mlx5_txq.c | 6 +++\n 6 files changed, 80 insertions(+), 10 deletions(-)" }
