David Anderson c9ec51e475 dhcp4: fix portable Conn initialization and packet transmission.
Conn is supposed to accept "" to mean "listen for DHCP on all interfaces",
but portableConn didn't correctly handle that.

And I got the comparison wrong on ifidx in the portable send function, so
packets got sent out entirely the wrong interface :(.
