How exactly? What does knowing the MAC address get anybody?
If this is the MAC address of the WAN side of the router, then your
ISP knows it, and anybody else on that subnet knows it. Dunno what
they'd ever do with it, and nobody outside of the LAN can do anything
with it.
On the wireless side, it's sprayed across the countryside...
I don't get what your concern is.
