This is both more efficient (because the knobs' bool is only updated whenever Node is changed, rarely) and also gets us one step closer to removing a case of storing a netmap.NetworkMap in magicsock. (eventually we want to phase out much of the use of that type internally) Updates #1909 Change-Id: I37e81789f94133175064fdc09984e4f3a431f1a1 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
