+Subject: [PATCH 1/2] libnetlink.h: Include <endian.h> explicitly for musl
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The code added in "f_flower: implement pfcp opts" uses h2be64,
+defined in endian.h. While this is pulled in around some corners
+for glibc (see below), that's not the case for musl and an
+explicit include is required there.
+
+. /usr/include/libmnl/libmnl.h
+.. /usr/include/sys/socket.h
+... /usr/include/bits/socket.h
+.... /usr/include/sys/types.h
+..... /usr/include/endian.h

+Subject: [PATCH 2/2] rdma.c: Add <libgen.h> include for basename on musl
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This include file is required on musl for availability of basename.
+
+Note that for glibc adding the include can have the side effect of
+switching from the GNU implementation of basename (which does not touch
+its argument) to the POSIX implementation (which under certain
+circumstances modifies the string passed to it, e.g. removing trailing
+slashes).
+
+This is safe however since the C99 and C11 standard says:
+> The parameters argc and argv and the strings pointed to by the argv
+> array shall be modifiable by the program, and retain their last-stored
+> values between program startup and program termination.
+(multiple google results, unfortunately no official reference link)
