1da177e4 LT |
9 | * Fixes: Mar 22 2001: Martin Bokaemper <mbokaemper@unispherenetworks.com> |
10 | * - reset skb->pkt_type on incoming packets when MAC was changed | |
11 | * - see that changed MAC is saddr for outgoing packets | |
12 | * Oct 20, 2001: Ard van Breeman: | |
13 | * - Fix MC-list, finally. | |
14 | * - Flush MC-list on VLAN destroy. | |
