Hello NetBSD gurus!!,
    As I am reading all the code related to network drivers I found that =
whenever if_flags field of (strict ifnet) is changed the if_start field =
is always reupdated.. why?Especially it is modified when IFF_OACTIVE=20
    May I know  when and why should anybody use this reupdation of the =
transmit routine?
    ( I am using if_de.c as my reference driver code. )
    Is there any other code also which I should refer along with if_de.c =
driver?
,Vikram
