◆ input
| netif_input_fn netif::input |
This function is called by the network device driver to pass a packet up the TCP/IP stack.

◆ linkoutput
| netif_linkoutput_fn netif::linkoutput |
This function is called by the ARP module when it wants to send a packet on the interface. This function outputs the pbuf as-is on the link medium.

◆ num
| u8_t netif::num |
number of this interface
Definition at line 196 of file netif.h.
Referenced by netif_add(), and netif_find().
◆ output
| netif_output_fn netif::output |
This function is called by the IP module when it wants to send a packet on the interface. This function typically first resolves the hardware address, then sends the packet.
Definition at line 151 of file netif.h.
Referenced by default_netif_init(), ip_forward(), ip_output_if(), TCPInterfaceInit(), and test_tcp_init_netif().
◆ state
| void* netif::state |
This field can be set by the device driver and could point to state information for the device.
