Subject: [PATCH] net/l2tp: remove unused macros to tame gcc warning
Date: Fri, 6 Nov 2020 13:29:54 +0800 [thread overview]
Message-ID: <1604640594-5750-1-git-send-email-alex.shi@linux.alibaba.com> (raw)
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.
