Why does " l2protocol peer stp" show up as an option if it's not supported?  Is that one of those things with ios that commands are there but don't work type of thing?   ...anyway, is MST (802.1s) supported on efp's?

EFPs don't support STP. You should be able to configure the interface as a regular trunk and then run STP across it.
Peering only applies to CDP, UDLD, LLDP, MSTP, LACP, PAgP, VTP, and DTP:
