Subject[PATCH] net/l2tp: remove unused macros to tame gcc warning
Date
There some unused macros cause gcc complain:

net/l2tp/l2tp_core.c:73:0: warning: macro "L2TP_HDRFLAG_P" is not used
[-Wunused-macros]
net/l2tp/l2tp_core.c:80:0: warning: macro "L2TP_SLFLAG_S" is not used
[-Wunused-macros]
net/l2tp/l2tp_core.c:81:0: warning: macro "L2TP_SL_SEQ_MASK" is not used
[-Wunused-macros]

Let's remove them to tame gcc.
