net/bnxt: support LRO This patch adds support to enable and disable LRO To support this feature, the driver creates an aggregator ring. When the hardware starts doing LRO, it sends a tpa_start completion. When the driver receives a tpa_end completion, it indicates that the LRO chaining is complete.

net/bnxt: add initial Tx code Initial implementation of tx_pkt_burst for transmit. bnxt_xmit_pkts() is the top level function that is called during Tx. bnxt_handle_tx_cp() is used to check and process the Tx completions generated for the Tx Buffer Descriptors sent by the hardware. This patch also adds code to allocate rings in the hardware. For each Tx queue allocated in the PMD driver, a corresponding ring in hardware will be created. Every time a Tx request is initiated via the bnxt_xmit_pkts() call, a Buffer Descriptor is created and is sent to the hardware via the associated Tx ring. On completing the Tx operation, the hardware will generates the status in the form of a completion. This completion is processed by the bnxt_handle_tx_cp() function.

This patch also adds code to allocate rings in the hardware. For each Tx queue allocated in the PMD driver, a corresponding ring in hardware will be created.

net/bnxt: add initial Rx code This patch adds initial implementation of rx_pkt_burst() function for Rx. bnxt_recv_pkts() is the top level function for doing Rx. This patch also adds code to allocate rings in the ASIC. For each Rx queue allocated in the PMD driver, a corresponding ring in hardware will be created. Every time a frame is received a Rx ring is selected based on the hardware configuration like RSS, MAC or VLAN, COS and such. The hardware uses a completion ring to indicate the availability of a packet. This patch also brings in functions like bnxt_init_one_rx_ring() bnxt_init_rx_ring_struct() which initializes various structures before a Rx can begin. bnxt_init_rxbds() initializes the Rx Buffer Descriptors while bnxt_alloc_rx_data() allocates a buffer in the host to receive the incoming packet.

net/bnxt: add initial Tx code Initial implementation of tx_pkt_burst for transmit. bnxt_xmit_pkts() is the top level function that is called during Tx. bnxt_handle_tx_cp() is used to check and process the Tx completions generated for the Tx Buffer Descriptors sent by the hardware. This patch also adds code to allocate rings in the hardware. For each Tx queue allocated in the PMD driver, a corresponding ring in hardware will be created. Every time a Tx request is initiated via the bnxt_xmit_pkts() call, a Buffer Descriptor is created and is sent to the hardware via the associated Tx ring. On completing the Tx operation, the hardware will generates the status in the form of a completion. This completion is processed by the bnxt_handle_tx_cp() function. Functions like bnxt_init_tx_ring_struct() and bnxt_init_one_tx_ring() are used to initialize various members of the structure before starting Tx operations.
