I've did something similar, but I used the macros LWIP_ARP_FILTER_NETIF and 
LWIP_ARP_FILTER_NETIF_FN() to execute the filter in the function 
ethernet_input() (in etharp.c), which is called from the correct thread, so no 
threading issues there (and I can directly walk the netif list and compare the 
current address without extra array allocation needed).
