That's -ENOSYS in net80211.c. It doesn't appear to be a problem with
the ath5k driver.

It looks like you're running up against some limitations of gPXE's 802.11 stack:

       if ( ( capab & ( IEEE80211_CAPAB_MANAGED | IEEE80211_CAPAB_ADHOC ) ) !=
            IEEE80211_CAPAB_MANAGED ) {
               DBGC ( dev, "802.11 %p cannot handle IBSS network\n", dev );
               return -ENOSYS;
       }

       if ( capab & IEEE80211_CAPAB_SPECTRUM_MGMT ) {
               DBGC ( dev, "802.11 %p cannot handle spectrum managed "
                      "network\n", dev );
               return -ENOSYS;
       }

Could you give another trace running with DEBUG=net80211 to determine
which of these it's coughing over? Some description of your network
might be helpful as well.

Thanks,
