gateway.d: Add scripts for network configuration This adds scripts to configure vlan and client network. This also adds sysctl settings to enable forwarding. Note: Devices specific properties are sourced from fff-network package. This creates a dependency on fff-boardname and fff-network. These properties should be located elsewhere in the future.

fff-gateway: Send ICMP errors using inbound ifaddr When using NATs and tunnels at the same time, the correct source address has to be used so the ICMP errors is sent through the NAT. This is necessary so the NAT can modify the ICMP payload so it is correctly identified by the destination host, which is required for PMTUD Fixes: #142 Signed-off-by: Fabian Bläse <fabian@blaese.de> Reviewed-by: Christian Dresel <fff@chrisi01.de> Reviewed-by: Robert Langhammer <rlanghammer@web.de> [bump PKG_RELEASE] Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
