batman-adv: fix tt_local_reset_flags() function
Currently the counter of tt_local_entry structures (tt_local_num) is incremented
each time the tt_local_reset_flags() is invoked causing the node to send wrong
TT_REPONSE packets containing a copy of non-initialised memory thus corrupting
other nodes global translation table and making higher level communication
impossible.

batman-adv: correctly set the data field in the TT_REPONSE packet
In the TT_RESPONSE packet, the number of carried entries is not correctly set.
This leads to a wrong interpretation of the packet payload on the receiver side
causing random entries to be added to the global translation table. Therefore
the latter gets always corrupted, triggering a table recovery all the time.

+ * Theory of operation
+ *
+ * The Au1000 MACs use a simple rx and tx descriptor ring scheme.
+ * There are four receive and four transmit descriptors. These
+ * descriptors are not in memory; rather, they are just a set of
+ * hardware registers.
+ *
+ * Since the Au1000 has a coherent data cache, the receive and
+ * transmit buffers are allocated from the KSEG0 segment. The
+ * hardware registers, however, are still mapped at KSEG1 to
+ * make sure there's no out-of-order writes, and that all writes
+ * complete immediately.
+ */
+
+ /*
+ * board-specific configurations
+ *
+ * PHY detection algorithm
+ *
+ * If phy_static_config is undefined, the PHY setup is
+ * autodetected:
+ *
+ * mii_probe() first searches the current MAC's MII bus for a PHY,
+ * selecting the first (or last, if phy_search_highest_addr is
+ * defined) PHY address not already claimed by another netdev.
+ *
+ * If nothing was found that way when searching for the 2nd ethernet
+ * controller's PHY and phy1_search_mac0 is defined, then
+ * the first MII bus is searched as well for an unclaimed PHY; this is
+ * needed in case of a dual-PHY accessible only through the MAC0's MII
+ * bus.
+ *
+ * Finally, if no PHY is found, then the corresponding ethernet
+ * controller is not registered to the network subsystem.

+ * most boards PHY setup should be detectable properly with the
+ * autodetection algorithm in mii_probe(), but in some cases (e.g. if
+ * you have a switch attached, or want to use the PHY's interrupt
+ * notification capabilities) you can provide a static PHY
+ * configuration here
+ *
+ * IRQs may only be set, if a PHY address was configured
