For ericsson support, pcuif_proto.h was added to osmo-bsc.git for a BSC-co-located PCU (osmo-bsc b4999b60d48bcbb5aa575973d068e07ab672e095).
Later on, the osmo-bsc pcuif_proto.h version was bumped to 0x08 (osmo-bsc f14cb3535cf469632b5da63f35b31aa79fd0c5c3).
Presumably osmo-bsc and osmo-pcu must interoperate and have matching pcuif versions.
Furthermore, if osmo-pcu is bumped, it must interoperate with osmo-bts, so osmo-bts.git's pcuif_proto.h also needs bumping.
It seems that the ericsson changes have not completely propagated into the respective master branches.
