-Subject: [PATCH] ntp: fix build with musl libc
-
-The configure script enables HAVE_LINUX_TIMESTAMPING_OPT_PKTINFO based
-on the existence of struct scm_ts_pktinfo and
-SOF_TIMESTAMPING_OPT_PKTINFO that were introduced in Linux kernel v4.13
-in the linux/net_tstamp.h kernel header. But this feature also requires
-SCM_TIMESTAMPING_PKTINFO that is defined in the socket.h header. musl
-libc provides its own version of socket.h, and as of musl version 1.1.16
-this macro is missing. Define this macro in the code as a temporary
-measure until musl is updated to its latest version.
