net: Print num_rx_queues imbalance warning only when there are allocated queues
BugLink: http://bugs.launchpad.net/bugs/591416 There are a number of network drivers (bridge, bonding, etc) that are not yet receive multi-queue enabled and use alloc_netdev(), so don't print a num_rx_queues imbalance warning in that case. Also, only print the warning once for those drivers that _are_ multi-queue enabled. Signed-off-by: Tim Gardner <tim.gardner@canonical.com> Acked-by: Eric Dumazet <eric.dumazet@gmail.com>
