The existing implementation is based on the several branches of tx_burst routines optimizied for most common sets of Tx hardware offload, supported by Mellanox NICs. It was not very easy to update, support and develop such kind of code - multiple branches impose multiple points to process. Also, many of frequently requested offload combinations are not supported yet in the most efficient way. That leads to selecting of not completely matching tx_burst routine and harms the performance. The new Tx datapath: - introduces the unified template for tx_burst routine to generate on compile time the most efficient instances, tuned for specified sets of hardware offloads - the best matching instance is chosen in run-time at sending queue configuration - almost all possible sets of Tx are supported - the best possible method to send each packet is chosen on runtime - introduces new devargs for more accurate tuning of data inlining Signed-off-by: Viacheslav Ovsiienko --- v4: - inline first mbufs for multi-segment packets - revert deprecated devargs support to not break device probing - HW VLAN insertion from WQE bug - rebase v3: - http://patches.dpdk.org/cover/56568/ - add reporting max number of segments in packet - minor fixes with inline data length setup - rebase on the current repo top v2: - http://patches.dpdk.org/cover/56451/ - minor performance issues resolved - typos in comments and docs v1: - http://patches.dpdk.org/patch/56091/ Viacheslav Ovsiienko (8): *** BLURB HERE *** Viacheslav Ovsiienko (8): net/mlx5: remove Tx datapath implementation net/mlx5: add Tx datapath related devargs net/mlx5: update Tx datapath definitions net/mlx5: extend NIC attributes query via DevX net/mlx5: add Tx datapath configuration and setup net/mlx5: introduce Tx burst routine template net/mlx5: implement Tx burst template net/mlx5: report supported max number of mbuf segments doc/guides/nics/mlx5.rst | 173 +- doc/guides/rel_notes/release_19_08.rst | 2 + drivers/net/mlx5/mlx5.c | 187 +- drivers/net/mlx5/mlx5.h | 14 +- drivers/net/mlx5/mlx5_defs.h | 36 +- drivers/net/mlx5/mlx5_devx_cmds.c | 102 +- drivers/net/mlx5/mlx5_ethdev.c | 95 +- drivers/net/mlx5/mlx5_prm.h | 357 ++- drivers/net/mlx5/mlx5_rxtx.c | 5338 ++++++++++++++++++++++---------- drivers/net/mlx5/mlx5_rxtx.h | 334 +- drivers/net/mlx5/mlx5_rxtx_vec.c | 175 -- drivers/net/mlx5/mlx5_rxtx_vec_neon.h | 289 -- drivers/net/mlx5/mlx5_rxtx_vec_sse.h | 284 -- drivers/net/mlx5/mlx5_txq.c | 289 +- 14 files changed, 4638 insertions(+), 3037 deletions(-)
