Subject: [PATCH] hostap: Revert a toxic part of the conversion to
 net_device_ops

From: Martin Decky <martin@...ky.cz>

As the hostap driver was converted to use net_device_ops, a mistake was 
made in hostap_main.c (commit 5ae4efbcd2611562a8b93596be034e63495706a5). 
Originally, the tx_queue_len was set to 0 for every other interface than 
HOSTAP_INTERFACE_MASTER, but the new fragment of code sets tx_queue_len to 
0 only for HOSTAP_INTERFACE_MASTER. The opposite of the previous 
behavior makes the driver to drop all packets in AP mode.

Change the way 0 is assigned to tx_queue_len according to the original 
logic.
