+Subject: [PATCH] lib/cap, cli/main: include switchtec/endian.h for musl
+
+lib/cap.c and cli/main.c call htole32()/le32toh()/le64toh() etc.
+without including inc/switchtec/endian.h, the project's own portable
+endian-conversion shim (already used by lib/diag.c, lib/switchtec.c,
+lib/pmon.c, lib/fw.c, lib/fabric.c, cli/mfg.c and cli/diag.c). On
+glibc this went unnoticed because some other transitively-included
+header happens to pull in <endian.h> as a side effect, but musl's
+headers don't have that side effect, so building with musl libc fails
+with "call to undeclared function 'htole32'" and friends. Add the
+missing include to both files so they pick up the same <endian.h>
+declarations (switchtec/endian.h just wraps <endian.h> on Linux,
+which musl provides unconditionally, unlike glibc which historically
+gated it behind feature-test macros).
+
