Existing qca-lacpd build fails with musl with below error:
error: 'caddr_t' undeclared (first use in this function)
  ifr.ifr_data = (caddr_t)&ecmd;

caddr_t is defined in <sys/types.h>, so we included this
header to fix build with the musl library.

For exported switch port, we use name of Linux network device to
identify it. So a new field "ifname" is added to specify name of
Linux network device.
