eth0?? That's the wired ethernet device, not wireless(?)

These seems to be correct, if you intend to kick out all associated (wireless) stations and in the future allow only station with hwaddr 01:02:03:04:05:06 to authenticate in the future. If you had any associated stations before issuing these commands, they should be deauthenticated and no frames should be accepted from them.

Ping from which host? If you are pinging from a station associated to the wireless device (wlan0), it should not be able to ping any hosts in eth0 after this (assuming you do not have another AP that would allow this, etc.).
