l2tp: generate correct module alias strings
Commit 65b32f801bfb ("uapi: move IPPROTO_L2TP to in.h") moved the definition of IPPROTO_L2TP from a define to an enum, but since __stringify doesn't work properly with enums, we ended up breaking the modalias strings for the l2tp modules: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-IPPROTO_L2TP alias: net-pf-2-proto-2-type-IPPROTO_L2TP alias: net-pf-10-proto-IPPROTO_L2TP alias: net-pf-10-proto-2-type-IPPROTO_L2TP Use the resolved number directly in MODULE_ALIAS_*() macros (as we already do with SOCK_DGRAM) to fix the alias strings: $ modinfo l2tp_ip l2tp_ip6 | grep alias alias: net-pf-2-proto-115 alias: net-pf-2-proto-115-type-2 alias: net-pf-10-proto-115 alias: net-pf-10-proto-115-type-2 Moreover, fix the ordering of the parameters passed to MODULE_ALIAS_NET_PF_PROTO_TYPE() by switching proto and type.
