Subject: [PATCH] vlan: fix musl build error
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

caddr_t is legacy BSD and should be avoided [1].

This fixes compile errors with the musl libc:

../src/ap/vlan_init.c: In function 'br_delif':
../src/ap/vlan_init.c:218:18: error: '__caddr_t' undeclared (first use in this function)
  ifr.ifr_data = (__caddr_t) args;

Upstream status: Pending [2]
