drivers/net/wan/x25_asy: Correct the ndo_open and ndo_stop functions
1. Move the lapb_register/lapb_unregister calls into the ndo_open/ndo_stop functions. This makes the LAPB protocol start/stop when the network interface starts/stops. When the network interface is down, the LAPB protocol shouldn't be running and the LAPB module shoudn't be generating control frames. 2. Move netif_start_queue/netif_stop_queue into the ndo_open/ndo_stop functions. This makes the TX queue start/stop when the network interface starts/stops. (netif_stop_queue was originally in the ndo_stop function. But to make the code look better, I created a new function to use as ndo_stop, and made it call the original ndo_stop function. I moved netif_stop_queue from the original ndo_stop function to the new ndo_stop function.) Cc: Martin Schiller <ms@dev.tdt.de> Signed-off-by: Xie He <xie.he.0141@gmail.com> Signed-off-by: David S.
