Jaehee Park b66eb3a6e4 net: ipv6: avoid accepting values greater than 2 for accept_untracked_na 
The accept_untracked_na sysctl changed from a boolean to an integer
when a new knob '2' was added. This patch provides a safeguard to avoid
accepting values that are not defined in the sysctl. When setting a
value greater than 2, the user will get an 'invalid argument' warning.

Fixes: aaa5f515b16b ("net: ipv6: new accept_untracked_na option to accept na only if in-network")
