Linksys BEFW11S4 v2 (WL-375P)

Overview
There are two FCC IDs for the BEFW11S4 v2, MXF-C901114 (Gemtek WL-375, PRISM 2.5) and MXF-C910308 (Gemtek WL-375P, PRISM 3). Some units list the FCC ID as just MXF-C901114 (see here) while others list both (see here). It is not known if the units which list both FCC IDs consist of a mix of both parts or are strictly the newer WL-375Ps. It is also not known if there is a version listing strictly the newer FCC ID (v2.1?).
