Detailed Description

Generic data structure used for all lwIP network interfaces. The following fields should be filled in by the initialization function for the device driver: hwaddr_len, hwaddr[], mtu, flags

Definition at line 136 of file netif.h.

◆ flags

◆ gw

ip_addr_t netif::gw

Definition at line 143 of file netif.h.

Referenced by netif_add(), netif_set_addr(), and netif_set_gw().

◆ hwaddr

u8_t netif::hwaddr[NETIF_MAX_HWADDR_LEN]

link level hardware address of this interface

Definition at line 190 of file netif.h.

Referenced by TCPInterfaceInit().

◆ hwaddr_len

u8_t netif::hwaddr_len

number of bytes used in hwaddr

Definition at line 188 of file netif.h.

Referenced by TCPInterfaceInit().

◆ 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 147 of file netif.h.

Referenced by netif_add().

◆ ip_addr

ip_addr_t netif::ip_addr

IP address configuration in network byte order

Definition at line 141 of file netif.h.

Referenced by ip4_addr_isbroadcast(), ip_input(), ip_output_if(), ip_route(), netif_add(), netif_set_ipaddr(), and test_tcp_init_netif().

◆ 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.

Definition at line 155 of file netif.h.

◆ mtu

u16_t netif::mtu

maximum transfer unit (in bytes)

Definition at line 186 of file netif.h.

Referenced by TCPInterfaceInit().

◆ name

char netif::name[2]

◆ netmask

◆ next

struct netif* netif::next

pointer to next in linked list

Definition at line 138 of file netif.h.

Referenced by ip_input(), ip_route(), netif_add(), netif_find(), netif_remove(), and test_tcp_init_netif().

◆ 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 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.
