qeth: optimize IP handling in rx_mode callback
In layer3 mode of the qeth driver, multicast IP addresses from struct net_device and other type of IP addresses from other sources require mapping to the OSA-card. This patch simplifies the IP address mapping logic, and changes imple- mentation of ndo_set_rx_mode callback and ip notifier events. Addresses are stored in private hashtables instead of lists now. It allows hardware registration/removal for new/deleted multicast addresses only. Signed-off-by:Lakhvich Dmitriy <ldmitriy@ru.ibm.com> Signed-off-by:
