◆ hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

Definition at line 309 of file netif.h.

◆ input

netif_input_fn netif::input

This function is called by the network device driver to pass a packet up the TCP/IP stack.

Definition at line 252 of file netif.h.

◆ linkoutput

netif_linkoutput_fn netif::linkoutput

This function is called by ethernet_output() when it wants to send a packet on the interface. This function outputs the pbuf as-is on the link medium.
