/**
* LWIP_HOOK_ETHARP_GET_GW(netif, dest):
* - called from etharp_output() (IPv4)
* - netif: the netif used for sending
* - dest: the destination IPv4 address
* Returns the IPv4 address of the gateway to handle the specified destination
* IPv4 address. If NULL is returned, the netif's default gateway is used.
* The returned address MUST be reachable on the specified netif!
* This function is meant to implement advanced IPv4 routing together with
* LWIP_HOOK_IP4_ROUTE(). The actual routing/gateway table implementation is
* not part of lwIP but can e.g. be hidden in the netif's state argument.
