Since this is such a common paradigm, this functionality is better suited to being inside the core ethdev API. The new APIs in the ethdev library are: * rte_eth_tx_buffer - buffer up a single packet for future transmission * rte_eth_tx_buffer_flush - flush any unsent buffered packets * rte_eth_tx_buffer_set_err_callback - set up a callback to be called in case transmitting a buffered burst fails. By default, we just free the unsent packets. As well as these, an additional reference callback is provided, which frees the packets (as the default callback does), as well as updating a user-provided counter, so that the number of dropped packets can be tracked. The internal buffering of packets for TX in sample apps is no longer needed, so this patchset also replaces this code with calls to the new rte_eth_tx_buffer* APIs in: * l2fwd-jobstats * l2fwd-keepalive * l2fwd * l3fwd-acl * l3fwd-power * link_status_interrupt * client_server_mp * l2fwd_fork * packet_ordering * qos_meter Tomasz Kulasek (2): ethdev: add buffered tx api examples: sample apps rework to use buffered tx api config/common_bsdapp | 1 + config/common_linuxapp | 1 + examples/l2fwd-jobstats/main.c | 73 ++----- examples/l2fwd-keepalive/main.c | 79 ++------ examples/l2fwd/main.c | 80 ++------ examples/l3fwd-acl/main.c | 64 +----- examples/l3fwd-power/main.c | 63 +----- examples/link_status_interrupt/main.c | 83 ++------ .../client_server_mp/mp_client/client.c | 77 +++---- examples/multi_process/l2fwd_fork/main.c | 81 ++------ examples/packet_ordering/main.c | 62 +++--- examples/qos_meter/main.c | 46 +---- lib/librte_ether/rte_ethdev.c | 63 +++++- lib/librte_ether/rte_ethdev.h | 211 +++++++++++++++++++- lib/librte_ether/rte_ether_version.map | 8 + 15 files changed, 445 insertions(+), 547 deletions(-) -- 1.7.9.5
