Subject: Added everything protocols need to know about multiple routing tables,
X-Git-Tag: v1.2.0~1648
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7dc4827c968053e45bcb7f145e9986eeb20c993b;p=thirdparty%2Fbird.git

Added everything protocols need to know about multiple routing tables,
i.e. struct proto now contains field 'table' pointing to routing table
the protocol is attached to. Use this instead of &master_table.

Modified all protocols except the kernel syncer to use this field.
