[PATCH v05 69/72] uapi rose.h: glibc netrose/rose.h header file compatibility fixes

From: Mikko Rapeli
Date: Mon Aug 22 2016 - 15:10:57 EST


Fixes these userspace compile errors and warnings when glibc
netrose/rose.h is included before linux/rose.h:

linux/rose.h:25:0: warning: "SIOCRSGCAUSE" redefined
linux/rose.h:26:0: warning: "SIOCRSSCAUSE" redefined
linux/rose.h:27:0: warning: "SIOCRSL2CALL" redefined
linux/rose.h:28:0: warning: "SIOCRSSL2CALL" redefined
linux/rose.h:29:0: warning: "SIOCRSACCEPT" redefined
linux/rose.h:30:0: warning: "SIOCRSCLRRT" redefined
linux/rose.h:31:0: warning: "SIOCRSGL2CALL" redefined
linux/rose.h:32:0: warning: "SIOCRSGFACILITIES" redefined
linux/rose.h:47:3: error: conflicting types for ârose_addressâ
linux/rose.h:49:8: error: redefinition of âstruct sockaddr_roseâ
linux/rose.h:57:8: error: redefinition of âstruct full_sockaddr_roseâ
linux/rose.h:65:8: error: redefinition of âstruct rose_route_structâ
linux/rose.h:74:8: error: redefinition of âstruct rose_cause_structâ
linux/rose.h:79:8: error: redefinition of âstruct rose_facilities_structâ
