help
B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
a routing protocol for multi-hop ad-hoc mesh networks. The
networks may be wired or wireless. See
https://www.open-mesh.org/ for more information and user space
tools.
config BATMAN_ADV_BATMAN_V
bool "B.A.T.M.A.N. V protocol (experimental)"
depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y)
default n
help
This option enables the B.A.T.M.A.N. V protocol, the successor
of the currently used B.A.T.M.A.N. IV protocol. The main
changes include splitting of the OGM protocol into a neighbor
discovery protocol (Echo Location Protocol, ELP) and a new OGM
Protocol OGMv2 for flooding protocol information through the
network, as well as a throughput based metric.
B.A.T.M.A.N. V is currently considered experimental and not
compatible to B.A.T.M.A.N. IV networks.
config BATMAN_ADV_BLA
bool "Bridge Loop Avoidance"
depends on BATMAN_ADV && INET
default y
help
This option enables BLA (Bridge Loop Avoidance), a mechanism
to avoid Ethernet frames looping when mesh nodes are connected
to both the same LAN and the same mesh. If you will never use
more than one mesh node in the same LAN, you can safely remove
this feature and save some space.
config BATMAN_ADV_DAT
bool "Distributed ARP Table"
depends on BATMAN_ADV && INET
default n
help
This option enables DAT (Distributed ARP Table), a DHT based
mechanism that increases ARP reliability on sparse wireless
mesh networks. If you think that your network does not need
this option you can safely remove it and save some space.
config BATMAN_ADV_NC
bool "Network Coding"
depends on BATMAN_ADV
default n
help
This option enables network coding, a mechanism that aims to
increase the overall network throughput by fusing multiple
packets in one transmission.
Note that interfaces controlled by batman-adv must be manually
configured to have promiscuous mode enabled in order to make
network coding work.
If you think that your network does not need this feature you
can safely disable it and save some space.
config BATMAN_ADV_MCAST
bool "Multicast optimisation"
depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y)
default n
help
This option enables the multicast optimisation which aims to
reduce the air overhead while improving the reliability of
multicast messages.
config BATMAN_ADV_DEBUGFS
bool "batman-adv debugfs entries"
depends on BATMAN_ADV
depends on DEBUG_FS
default y
help
Enable this to export routing related debug tables via debugfs.
The information for each soft-interface and used hard-interface can be
found under batman_adv/
If unsure, say Y.
config BATMAN_ADV_DEBUG
bool "B.A.T.M.A.N. debugging"
depends on BATMAN_ADV_DEBUGFS
help
This is an option for use by developers; most people should
say N here. This enables compilation of support for
outputting debugging information to the kernel log. The
output is controlled via the module parameter debug.

bridge: move to workqueue gc
Move the fdb garbage collector to a workqueue which fires at least 10
milliseconds apart and cleans chain by chain allowing for other tasks
to run in the meantime. When having thousands of fdbs the system is much
more responsive. Most importantly remove the need to check if the
matched entry has expired in __br_fdb_get that causes false-sharing and
is completely unnecessary if we cleanup entries, at worst we'll get 10ms
of traffic for that entry before it gets deleted.
