Subject: batman-adv: bla: use netif_rx_ni when not in interrupt context
|
|
|
|
batadv_bla_send_claim() gets called from worker thread context through
|
|
batadv_bla_periodic_work(), thus netif_rx_ni needs to be used in that
|
|
case. This fixes "NOHZ: local_softirq_pending 08" log messages seen
|
|
when batman-adv is enabled.
|
|
|
|
Fixes: a9ce0dc43e2c ("batman-adv: add basic bridge loop avoidance code")
