This is > unnecessary and will lead a very high order of page allocation when has a high > possibility to fail. Solving this by creating a one queue net device when > userspace only use one queue and also reduce MAX_TAP_QUEUES to > DEFAULT_MAX_NUM_RSS_QUEUES which can guarantee the success of > the allocation. > > Reported-by: Dirk Hohndel <dirk@...ndel.org> > Cc: Eric Dumazet <eric.dumazet@...il.com> > Cc: David Woodhouse <dwmw2@...radead.org> > Cc: Michael S.
