ip6_privacy
Description:
Configure IPv6 Privacy Extensions for SLAAC, described in RFC4941.
If enabled, it makes the kernel generate a temporary IPv6 address in addition to the public one generated from MAC address via modified EUI-64. This enhances privacy, but could cause problems in some applications, on the other hand. The permitted values are: 0: disabled, 1: enabled (prefer public address), 2: enabled (prefer temporary addresses).
