5G FAPI: P19 RF and digital frontend control API

This P19 interface specification serves as a companion to the 5G FAPI P5/P7 specification. Besides enabling the fast, dynamic control of the FEU, one of the primary goals of P19 is to facilitate network virtualization by allowing stack and FEU solutions from different vendors to bind together easily. The concept applies to both the all-in-one small cell solutions where the upper, the lower layers and the FEU are all colocated, as well as the disaggregated solutions where they may reside at different physical locations.
