Also it seems, that ARP traffic traverses the bridge. When I ping a device
plugged into eth1 from a device on the wlan, tcpdump on eth1 shows request and
answer as neverending sequence. So the ARP packets must go from worksation2 >
wlan > wlan0 > br0 > eth1 > WDShareSpace and back.
# tcpdump -envfi eth1
tcpdump: WARNING: eth1: no IPv4 address assigned
tcpdump: listening on eth1, link-type EN10MB (Ethernet), capture size 96 bytes
