Definition in file rte_bpf_ethdev.h.

Function Documentation

void rte_bpf_eth_rx_unload ( uint16_t  port,
uint16_t  queue 
)

Unload previously loaded BPF program (if any) from given RX port/queue and remove appropriate RX port/queue callback.

Parameters
portThe identifier of the ethernet port
queueThe identifier of the RX queue on the given port
void rte_bpf_eth_tx_unload ( uint16_t  port,
uint16_t  queue 
)

Unload previously loaded BPF program (if any) from given TX port/queue and remove appropriate TX port/queue callback.

Parameters
portThe identifier of the ethernet port
queueThe identifier of the TX queue on the given port
int rte_bpf_eth_rx_elf_load ( uint16_t  port,
uint16_t  queue,
const struct rte_bpf_prm prm,
const char *  fname,
const char *  sname,
uint32_t  flags 
)

Load BPF program from the ELF file and install callback to execute it on given RX port/queue.

Parameters
portThe identifier of the ethernet port
queueThe identifier of the RX queue on the given port
fnamePathname for a ELF file.
snameName of the executable section within the file to load.
prmParameters used to create and initialise the BPF execution context.
flagsFlags that define expected behavior of the loaded filter (i.e. jited/non-jited version to use).
Returns
Zero on successful completion or negative error code otherwise.
