[IPROUTE]: Add support for larger number of routing tables
Support support for 2^32 routing tables by using the new RTA_TABLE
attribute for specifying tables > 255 and intepreting it if it is
sent by the kernel.
When tables > 255 are used on a kernel not supporting it an error will
occur because of the unknown netlink attribute.
