This part of the change appears to have broken i386 with the following:

 /usr/src/sys/modules/wl/../../dev/wl/if_wl.c:1360:24: error: expression is not assignable
         ifr_data_get_ptr(ifr) = (caddr_t) (sc->nwid[0] << 8 | sc->nwid[1]);
        ~~~~~~~~~~~~~~~~~~~~~ ^
 1 error generated.
 --- if_wl.o ---
 *** [if_wl.o] Error code 1

 make[4]: stopped in /usr/src/sys/modules/wl
 1 error
