Well, fib_tables[] is the array of pointers we use, indexed by table ID. That's statically built into the kernel image, how large would you like to make it? This is controlled by RT_TABLE_MAX, which BTW is the local table and some apps may depend upon that relationship. I definitely don't like the idea of making the pointer array for fib_tables[] dynamically allocated, that means this change has a real cost for everyone, not just the people who want more than 256 table IDs. And the list of implications at the implementation level goes on and on. See why there is always so little interest and incentive to make this change? And perhaps even what you're trying to accomplish can be done with some other machinery. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
