[PATCH v05 68/72] uapi ax25.h: glibc netax25/ax25.h header file compatibility fixes
From: Mikko Rapeli
Date: Mon Aug 22 2016 - 15:24:05 EST
Fixes these userspace compile error when glibc netax25/ax25.h is included
before linux/ax25.h:
linux/ax25.h:28:0: warning: "SIOCAX25GETUID" redefined
linux/ax25.h:38:0: warning: "SIOCAX25GETINFO" redefined
linux/ax25.h:47:3: error: conflicting types for âax25_addressâ
linux/ax25.h:49:8: error: redefinition of âstruct sockaddr_ax25â
linux/ax25.h:58:8: error: redefinition of âstruct full_sockaddr_ax25â
linux/ax25.h:63:8: error: redefinition of âstruct ax25_routes_structâ
linux/ax25.h:70:8: error: redefinition of âstruct ax25_route_opt_structâ
linux/ax25.h:77:8: error: redefinition of âstruct ax25_ctl_structâ
linux/ax25.h:98:8: error: redefinition of âstruct ax25_info_structâ
linux/ax25.h:111:8: error: redefinition of âstruct ax25_fwd_structâ
