The next patch will enable listeners of the FIB notification chain to request a dump of the FIB tables. However, since RTNL isn't taken during the dump, it's possible for the FIB tables to change mid-dump, which will result in inconsistency between the listener's table and the kernel's. Allow listeners to know about changes that occurred mid-dump, by adding a change sequence counter to each net namespace. The counter is incremented just before a notification is sent in the FIB chain. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
