    ifconfig: ifieee80211: print bssid name
    
    In certain setups (e.g., autonomous APs) it is extremly helpful to have
    a way to map the BSSIDs to names for both normal status output as well
    as the scan list.  This often allows a quicker overview than remembering
    (or manually looking up) BSSIDs.
    Call ether_ntohost() on the bssid and consult /etc/ethers
    and print "(name)" after the bssid for the status output and "(name)"
    at the end of the line after the IE list.
