Thankfully the iteration in t3_config_rss() stops > anyway, but in the last iteration the check for the terminator > is an out of bounds read. > > Add the missing terminator to rspq_map[]. > > Reported-by: Jan Stancek <jstancek@...hat.com> > Signed-off-by: Michal Schmidt <mschmidt@...hat.com> Applied.
