ORBIT-USER: ad-hoc BSSID partitioning fix

[Einar Vollset]

I've made a similar fix to the latest madwifi (0.9.2) source in case  
someone prefers the bleeding edge :-):

Assuming you've unpacked madwifi-0.9.2.tar.gz in your home directory,  
the file is:

~/madwifi-0.9.2/net80211/ieee80211_node.c

The change is roughly on line 305:

Before:
       if (vap->iv_opmode == IEEE80211_M_IBSS) {
                 vap->iv_flags |= IEEE80211_F_SIBSS;
                 ni->ni_capinfo |= IEEE80211_CAPINFO_IBSS;       /*  
XXX */
                 if (vap->iv_flags & IEEE80211_F_DESBSSID)
                         IEEE80211_ADDR_COPY(ni->ni_bssid, vap- 
 >iv_des_bssid);
                 else
                         ni->ni_bssid[0] |= 0x02;        /* local bit  
for IBSS */
         }


After:
      if (vap->iv_opmode == IEEE80211_M_IBSS) {
		int i;
                 vap->iv_flags |= IEEE80211_F_SIBSS;
                 ni->ni_capinfo |= IEEE80211_CAPINFO_IBSS;       /*  
XXX */
                 if (vap->iv_flags & IEEE80211_F_DESBSSID)
                         IEEE80211_ADDR_COPY(ni->ni_bssid, vap- 
 >iv_des_bssid);
                 else
                         ni->ni_bssid[0] |= 0x02;        /* local bit  
for IBSS */
                 for(i=0; i<IEEE80211_ADDR_LEN;i++){
                     ni->ni_bssid[i] = ni->ni_essid[i % ni->ni_esslen];
                 }
         }



then simply make and copy the new modules as in Chris' tutorial and  
you're done. Note that this hasn't
been tested extensively, but appears to work on roughly 20 nodes on  
the main grid.

Cheers,

Einar
