Error description
There are two symptoms. One is that the multicast addresses that have been registered can be "forgotten" resulting in packets for those addresses not being passed through to the LPAR. The other symptom is a crash with the following stack trace: pvthread+015000 STACK: [04221F64]t3_mac_set_rx_mode+0001E4 (01005E7F18010008, 01005E7F18010000 [??]) [0421EAA8]set_rxmode+000028 (??)
