+Subject: [PATCH] fix include to find SIOCGSTAMP with latest kernel
+
+In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
+the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
+Instead it provides only SIOCGSTAMP_OLD.
+
+The linux/sockios.h header now defines SIOCGSTAMP using either
+SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. This linux only
+header file is not pulled so we get a build failure.
+
+./state_bcm.c: In function 'state_bcm':
+./state_bcm.c:91:16: error: 'SIOCGSTAMP' undeclared (first use in this function); did you mean 'SIOCGARP'?
+   if(ioctl(sc, SIOCGSTAMP, &tv) < 0) {
