IPVS: Modify the SH scheduler to use weights

	  If you want to compile it in kernel, say Y. To compile it as a

	  module, choose M here. If unsure, say N.

comment 'IPVS SH scheduler'

config IP_VS_SH_TAB_BITS

	int "IPVS source hashing table size (the Nth power of 2)"

	range 4 20

	default 8

	---help---

	  The source hashing scheduler maps source IPs to destinations

	  stored in a hash table. This table is tiled by each destination

	  until all slots in the table are filled. When using weights to

	  allow destinations to receive more connections, the table is

	  tiled an amount proportional to the weights specified. The table

	  needs to be large enough to effectively fit all the destinations

	  multiplied by their respective weights.

 * server is dead or overloaded, the load balancer can bypass the cache

 * server and send requests to the original server directly.

 *

 * The weight destination attribute can be used to control the

 * distribution of connections to the destinations in servernode. The

 * greater the weight, the more connections the destination

 * will receive.
