I fail to see where bh is disabled. ovs_dp_process_received_packet() is
called with rcu_read_lock...

It happens in __dev_queue_xmit(), which does rcu_read_lock_bh().

On tx yes. But how about rx? I don't see it there (rx_handler path).
Maybe I'm missing something.

For this code path they are one in the same.
