Re: packet injection and Suggested fields -

Hi All,

   A comment about packet injection.

   Given a "real" monitor mode (all packets and packet fragments).
   AND a REAL injection mode,

   MOST ALL of the driver packet bugs could be ELIMINATED [bypassed] with
the proper driver.

   Also ANY number of APs can be created. Mesh can be made to really work
reliably, etc.

   Subject, as mentioned, to radio [channel changing] limitations of
course.

   warm regards from COLD NH USA,
   wiz
