Ethernet
["raw" APIs]

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 (lwip_ieee_eth_type)

Returns:

ERR_OK if the packet was sent, any other err_t on failure
