Perhaps a little more involved, but I think it would also be good to bring if_hw_addr into compatibility with the sources from which is drawn such as: ether.h: u_int8_t ether_dhost[ETHER_ADDR_LEN]; ether.h: u_int8_t ether_shost[ETHER_ADDR_LEN]; token.h: u_int8_t token_dhost[TOKEN_RING_MAC_LEN]; token.h: u_int8_t token_shost[TOKEN_RING_MAC_LEN];
so change all declarations from "char" to "u_int8_t".
Attached.

Hi,
Running iftop-1.0pre4 I noticed my MAC address getting printed with some bytes (the "negative" ones) sign-extended into 32 bits (i.e. with "ffffff" prefixed). The below patch restores more a conventional-looking format.
Thanks, Zev Weiss
