The ICMPv6 packet is stored in network byte order. It must therefore always be converted to host byteorder before it can be used in calculations. Signed-off-by: Sven Eckelmann <sven@narfation.org> |

gluon-radv-filterd
This package drops all incoming router advertisements except for the default router with the best metric according to B.A.T.M.A.N. advanced.
Note that advertisements originating from the node itself (for example via gluon-radvd) are not affected and considered at all.
"Best" router
The best router is determined by the TQ that is reported for its originator by B.A.T.M.A.N. advanced. If, for some reason, another gateway with a better TQ appears or an existing gateway increases its TQ above that of the chosen gateway, the chosen gateway will remain selected until the better gateway has a TQ value at least X higher than the selected gateway. This is called hysteresis, and X can be specified on the commandline/via UCI/the site.conf and defaults to 20 (just as for the IPv4 gateway selection feature built into B.A.T.M.A.N. advanced).
"Local" routers
The package has functionality to assign "local" routers, i.e. those connected
via cable or WLAN instead of via the mesh (technically: appearing in the
transtable_local), a fake TQ of 512 so that they are always preferred.
However, if used together with the gluon-ebtables-filter-ra-dhcp package,
these router advertisements are filtered anyway and reach neither the node nor
any other client. You currently have to disable the package or insert custom
ebtables rules in order to use local routers.
