tipc: increase size of tipc discovery messages
The payload area following the TIPC discovery message header is an opaque area defined by the media. INT_H_SIZE was enough for Ethernet/IB/IPv4 but needs to be expanded to carry IPv6 addressing information. Signed-off-by: Erik Hugne <erik.hugne@ericsson.com> Signed-off-by: David S.
