netlink: make Netlink socket receive buffer 4x larger
Under high load I observed that Netlink socket buffer constantly
fills up for daemons listening for Conntrack Table notifications:
netlink_notifier|WARN|netlink receive buffer overflowed
This patch mitigates the problem by increasing socket
receive buffer size. Ideally we should try to calculate
buffer size required, but it would be more sophisticated
solution than simply increasing buffer size.
