Currently i don't see the IP accounting feature is conman for WiFi Clients.
I like to contribute the implementation for IP Accounting for WiFi Clients. Can

I like to understand why to check whether MAC is already present or not in the
hash table.
My understanding is once the MAC is authenticated and MAC is added to the Hash
table, then the DHCP server start leasing the IP to the client, after
successful leasing lease_added method i called. If my understanding is correct,
what is the use of the adding MAC address check and not present condition. if
the execution reaches lease_added method, that means MAC address is already
inserted in the hash table.
Can some one help here to understand the logic
/**********tethering.c(lease_added)******************************/
DBG("ip address for lease added:%s",ip_addr);
struct tether_client * teth_cli = NULL;
if(true == g_hash_table_lookup_extended(clients_table, mac_addr, NULL,
&teth_cli))
{
DBG("modifying ip address for %s mac address from hash
table",mac_addr);
g_free(teth_cli->ip);
teth_cli->ip = g_strdup(ip_addr);
}
else
{
DBG("no entry present for %s mac address",mac_addr);
teth_cli = tether_client_create(ip_addr);
if (teth_cli)
{
char * mac;
mac = g_strdup(mac_addr);
g_hash_table_insert(clients_table, mac, teth_cli);
}
}
