Which OpenWRT packages can be removed safely?

[Shots_Fired]

I'd like to install some packages on my TL-MR3040 v2, but the OpenWRT firmware image downloaded from the DSLRdashboard site only has ~85kb of free space available. I'm wondering which packages I can remove without messing with the function of ddashboard, or the device's ability to connect to the camera, Wifi, and ethernet.

I figure that the PPP module should be the first to go, since I'm never going to be using this device to connect to a modem. Anything else people have used to strip OpenWRT down to its Dashboard essentials?

Thanks

Probably you could remote the IPv6 packages if you don't need it.
