  Modified files:
    sys/net              if.h 
  Log:
  Add a macro to accurately calculate the length of a struct ifreq when
  it contains an address.  This can replace all the myriad (wrong) ways
  in which this task is performed in the current system.  As an added
  bonus, since it's a macro, then third-party software vendors have an easy
  way to tell whether it's there or not.  (This will become necessary
  when sizeof(struct sockaddr) is increaased, and also when additional
  fields are added to struct ifreq.)
