Function Documentation
Process received ethernet frames.
Using this function instead of directly calling ip_input and passing ARP frames through etharp in ethernetif_input, the ARP cache is protected from concurrent access.
Don't call directly, pass to netif_add() and call netif->input().
- Parameters:
-
p the received packet, p->payload pointing to the ethernet header netif the network interface on which the packet was received
- See also:
- LWIP_HOOK_UNKNOWN_ETH_PROTOCOL
- ETHARP_SUPPORT_VLAN
- LWIP_HOOK_VLAN_CHECK
Send an ethernet packet on the network using netif->linkoutput(). The ethernet header is filled in before sending.
- See also:
- LWIP_HOOK_VLAN_SET
- Parameters:
-
netif the lwIP network interface on which to send the packet p the packet to send. pbuf layer must be PBUF_LINK. src the source MAC address to be copied into the ethernet header dst the destination MAC address to be copied into the ethernet header eth_type ethernet type (eth_type)
- Returns:
- ERR_OK if the packet was sent, any other err_t on failure
