| Set max burst size property for doca_eth_txq. This value dictates the maximal number of packets the HW can handle at the same time. can only be called before calling doca_ctx_start(). More... | |
| DOCA_EXPERIMENTAL doca_error_t | doca_eth_txq_set_max_send_buf_list_len (struct doca_eth_txq *eth_txq, uint32_t max_send_buf_list_len) |

| DOCA_EXPERIMENTAL doca_error_t | doca_eth_txq_set_metadata_num (struct doca_eth_txq *eth_txq, uint8_t metadata_num) |
| Set metadata number for doca_eth_txq. This value is the number of metadata per packet. can only be called before calling doca_ctx_start(). More... | |
| DOCA_EXPERIMENTAL doca_error_t | doca_eth_txq_set_mss (struct doca_eth_txq *eth_txq, uint16_t mss) |
| Set the Maximum Segment Size for doca_eth_txq. This value will be used per LSO send task / task_batch unless user overrides it (by setting MSS on the specific task / task_batch). This value is the maximum data size that can be sent in each segment of the LSO packet. can only be called before calling doca_ctx_start(). More... | |

| Set offload for the calculation of IPv4 checksum (L3) on transmitted packets. If the users enables L3 checksum offloading, then the HW will calculate the checksum value and write it into the specific field in the packet. This offload is enabled/disabled to every task / task_batch by default. User can change this by modifying the ol_flag value (See "enum doca_eth_txq_ol_flags"). can only be called before calling doca_ctx_start(). More... | |

| Set offload for the calculation of TCP/UDP checksum (L4) on transmitted packets. If the users enables L4 checksum offloading, then the HW will calculate the checksum value and write it into the specific field in the packet. This offload is enabled/disabled to every task / task_batch by default. User can change this by modifying the ol_flag value (See "enum doca_eth_txq_ol_flags"). can only be called before calling doca_ctx_start(). More... | |
| DOCA_EXPERIMENTAL doca_error_t | doca_eth_txq_set_wait_on_time_offload (struct doca_eth_txq *eth_txq) |
