Functions

struct lld_ethhdr __attribute__ ((packed))
 
int cb_lld_init_devs_table (lld_ethdev_t *ethdevs, uint32_t ndevs, uint32_t enet_type, uint32_t instance_id)
 Initialize a LLD device table. More...
 
int cb_socket_set_lldcfg_update_cb (cb_socket_lldcfg_update_cb_t lldcfg_update_cb)
 This function sets the callback for updating LLD config parameters. It enables the user to update config parameters for the Enet LLD layer that are not supported by the CB socket. It is important to note that this function should only be called once. More...
 
int cb_lld_netdev_to_macport (const char *netdev)
 Convert net device name to mac port. More...
 
int cb_lld_sendto (CB_SOCKET_T sfd, void *sdata, int psize, int flags, const CB_SOCKADDR_LL_T *addr, int addrsize)
 Send a TX ethernet L2 packet. More...
 
int cb_lld_sendto_scatter (CB_SOCKET_T sfd, LLDEnetFrameScatter_t *frame, const CB_SOCKADDR_LL_T *addr)
 Send a TX ethernet L2 packet in the scatter way. More...
 
int cb_lld_recv (CB_SOCKET_T sfd, void *buf, int size, CB_SOCKADDR_LL_T *addr, int addrsize)
 Receive a RX ethernet L2 packet. This should be called after a rxnotify_cb is invoked. More...
 
int cb_lld_recv_zerocopy (CB_SOCKET_T sfd, LLDEnetRecvCb_t cblld_recv_cb, void *cbarg)
 Receive a RX ethernet L2 packet n the zero-copy way. This should be called after a rxnotify_cb is invoked. More...
 
int cb_lld_set_txnotify_cb (CB_SOCKET_T sfd, void(*txnotify_cb)(void *arg), void *arg)
 Set the TX notify callback that is invoked when an TX packet is sent successfully. More...
 
int cb_lld_set_rxnotify_cb (CB_SOCKET_T sfd, void(*rxnotify_cb)(void *arg), void *arg)
 Set the RX notify callback that is invoked when an RX packet is ready to be received. More...
