[PATCH 4.4 43/91] hsr: set .netnsok flag

[Greg Kroah-Hartman]

From: Taehee Yoo <ap420073@xxxxxxxxx>

[ Upstream commit 09e91dbea0aa32be02d8877bd50490813de56b9a ]

The hsr module has been supporting the list and status command.
(HSR_C_GET_NODE_LIST and HSR_C_GET_NODE_STATUS)
These commands send node information to the user-space via generic netlink.
But, in the non-init_net namespace, these commands are not allowed
because .netnsok flag is false.
So, there is no way to get node information in the non-init_net namespace.

Fixes: f421436a591d ("net/hsr: Add support for the High-availability Seamless Redundancy protocol (HSRv0)")
