From f8214865a55f805e65c33350bc0f1eb46dd8433d Mon Sep 17 00:00:00 2001 From: Martin Hundebøll Date: Fri, 20 Apr 2012 17:02:45 +0200 Subject: batman-adv: Add get_ethtool_stats() support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Added additional counters in a bat_stats structure, which are exported through the ethtool api. The counters are specific to batman-adv and includes: forwarded packets and bytes management packets and bytes (aggregated OGMs at this point) translation table packets New counters are added by extending "enum bat_counters" in types.h and adding corresponding descriptive string(s) to bat_counters_strings in soft-iface.c. Counters are increased by calling batadv_add_counter() and incremented by one by calling batadv_inc_counter().

In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.

In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.

In that case the linker will see all non-static symbols of batman-adv and all other non-static symbols of the kernel. This could lead to symbol collisions. A prefix for the batman-adv symbols that defines their private namespace avoids such a problem.

The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.

As the bridge loop avoidance code now only considers the payload Ethernet destination, it may drop the DHCP request for clients which are claimed by other backbone gateways, because it falsely infers from the broadcast address that the right backbone gateway should havehandled the broadcast. Fix this by checking and delegating the batman-adv packet type used for transmission.
