     What you are calling packet injection (not reinjection) seems to 
sound like something that I overheard at the last wireless conference.  
Basically... when a base station recieves a wireless packet from a 
computer associated with it that has a corrupt CRC (not TCP/IP CRC, 
802.11 CRC) for security reasons the base station is supposed to shut 
down for a minute.  This "security feature" basically allows users to DoS 
a BaseStation with corrupt wireless CRC packets if they have raw access 
to the wireless card.  There was some reason they were doing this, I 
think it was to counter Brute Force attacks on the WEP password.  No idea 
though really... I think the shutting down for 1 minute thing is not the 
greatest of ideas though.  Anyway, that's all from me tonite...
