How to enable more than ~256 routing tables?

[Ben Greear <greearb@xxxxxxxxxxxxxxx>]

I would like to have a routing table per interface, and would like to support
1k interfaces or so (virtual interfaces like vlans, for instance).

I notice in rtnetlink.h there is this code:

enum rt_class_t
{
        RT_TABLE_UNSPEC=0,
/* User defined values */
        RT_TABLE_DEFAULT=253,
        RT_TABLE_MAIN=254,
        RT_TABLE_LOCAL=255
};
#define RT_TABLE_MAX RT_TABLE_LOCAL


Is it possible to just change the RT_TABLE_MAX to be higher and have 
256-????
be more /* User defined values */ ?

Thanks,
Ben
