Also, I am not sure we need to use all 128 bits of IPV6 address, maybe the 64
low order bits are enough ?
Well, maybe, but in IPv6, auto-configured addresses on an interface have
the same 64-bit LSBs. So, I'd keep as-is so far.
Hum... then maybe ipv6_addr_hash() in include/net/addrconf.h should be changed
as well
static __inline__ u8 ipv6_addr_hash(const struct in6_addr *addr)
{
__u32 word;
/*
* We perform the hash function over the last 64 bits of the address
* This will include the IEEE address token on links that support it.
*/
word = (__force u32)(addr->s6_addr32[2] ^ addr->s6_addr32[3]);
word ^= (word >> 16);
word ^= (word >> 8);
return ((word ^ (word >> 4)) & 0x0f);
}
