This refers to the number of hash buckets in the IPVS connection table.
This is configured at compile time by setting CONFIG_IP_VS_TAB_BITS,
the default is 12.
size = 2^CONFIG_IP_VS_TAB_BITS
Thus CONFIG_IP_VS_TAB_BITS = 12 -> size = 4096
CONFIG_IP_VS_TAB_BITS = 16 -> size = 65536
Note that this is the number of hash buckets, not the maximum
number of connections. A bucket can contain zero or more connections.
The maximum number of conenctions is only limited by the memory
available.
