[ Upstream commit 05d4487197b2b71d5363623c28924fd58c71c0b6 ]
Cited commit added the possible value of '2', but it cannot be set. Fix it by adjusting the maximum value to '2'. This is consistent with the corresponding IPv4 sysctl.
Before:
# sysctl -w net.ipv6.fib_multipath_hash_policy=2 sysctl: setting key "net.ipv6.fib_multipath_hash_policy": Invalid argument net.ipv6.fib_multipath_hash_policy = 2 # sysctl net.ipv6.fib_multipath_hash_policy net.ipv6.fib_multipath_hash_policy = 0
After:
# sysctl -w net.ipv6.fib_multipath_hash_policy=2 net.ipv6.fib_multipath_hash_policy = 2 # sysctl net.ipv6.fib_multipath_hash_policy net.ipv6.fib_multipath_hash_policy = 2
