My pr 11754 was not accepted by gnats, what's happened...
By the way, SIOCGIFADDR ioctl does not work on tx (SMC chip) network
driver. The SIOCGIFADDR ioctl [src/pci/if_tx.c, epic_ifioctl]
invokes ether_ioctl() [src/net/if_ethersubr.c]. Here, MAC address
is copied out, as follows.
bcopy(((struct arpcom *)ifp->if_softc)->ac_enaddr,
(caddr_t) sa->sa_data, ETHER_ADDR_LEN);
So, "struct arpcom arpcom" must be a first element of softc structure.
