When using nanosleep() in an userspace application we get a ratelimit warning NOHZ: local_softirq_pending 08 for 10 times. This patch replaces netif_rx() with netif_rx_ni() which has to be used from process/softirq context. The process/softirq context will be called from fakelb driver. See linux-kernel commit 481a819 for similar fix. Signed-off-by: Alexander Aring <alex.aring@gmail.com> --- net/mac802154/wpan.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
