http://read.cs.ucla.edu/click/elements/addressinfo You need to specify the
address in the following format:
AddressInfo(mauer 10.0.0.1 00-50-BA-85-84-A9);

click,recently I compile click on openwrt 8.09.2,but I can not
run the "access-point.click" successfully,some error happen at "FromHost(ap,

/conf/wifi/access-point.click,I
look at the code of "addressinfo.cc" and find the problem at
"AddressInfo::configure" function,the original code is
107    if (cp_ip_address(parts[j], &x.ip4.a))
108 NameInfo::define(NameInfo::T_IP_ADDR, this, parts[0], &x.ip4.a, 4);
109    else if (cp_ip_prefix(parts[j], x.ip4b.a, x.ip4b.p, false)) {
110 NameInfo::define(NameInfo::T_IP_PREFIX, this, parts[0], &x.ip4, 8);
111 if (x.ip4.a.s_addr & ~x.ip4.p.s_addr)
112    NameInfo::define(NameInfo::T_IP_ADDR, this, parts[0], &x.ip4.a, 4);
113    } else if (cp_ethernet_address(parts[j], x.ether))
114 NameInfo::define(NameInfo::T_ETHERNET_ADDR, this, parts[0], x.ether, 6);

my modify is
           if (cp_ethernet_address(parts[j], x.ether))
NameInfo::define(NameInfo::T_ETHERNET_ADDR, this, parts[0], x.ether, 6);
    if (cp_ip_address(parts[j], &x.ip4.a))
NameInfo::define(NameInfo::T_IP_ADDR, this, parts[0], &x.ip4.a, 4);
    else if (cp_ip_prefix(parts[j], x.ip4b.a, x.ip4b.p, false)) {
NameInfo::define(NameInfo::T_IP_PREFIX, this, parts[0], &x.ip4, 8);
if (x.ip4.a.s_addr & ~x.ip4.p.s_addr)
    NameInfo::define(NameInfo::T_IP_ADDR, this, parts[0], &x.ip4.a, 4);
    }

the problem of original code is when interpret the code
"AddressInfo(ap_bssid 10.0.0.1/8 ath1)" at "access-point.click" the program
will not store the mac addr of ath1 at the db,then when interpret the code
"FromHost(ap, ap_bssid, ETHER ap_bssid)" it first find the mac addr
of ap_bssid at the db,but failed,then it will get all the mac addr of the
system's interfaces,and try to get the mac addr of the interface named
"ap_bssid",of course it will fail.
Is my modification right?
