Driver/Card information: ------------------- 3c59x: Donald Becker and others. www.scyld.com/network/vortex.html 00:10.0: 3Com PCI 3c905C Tornado at 0xe000. Vers LK1.1.1600:10.0 3Com Corporation 3c905C-TX/TX-M [Tornado] (rev 78) ------------------- I tried: # ifconfig eth0 -mulicast And STILL the frame was processed. The linux/drivers/net/3c59x.c has this comment: /* Pre-Cyclone chips have no documented multicast filter, so the only multicast setting is to receive all multicast frames. At least the chip has a very clean way to set the mode, unlike many others. */ However, this card is Tornado, the latest rev, so this comment shouldn't apply. The families go: Vortex -> Boomerang -> Cyclone -> Tornado Also, I tried using the latest Donald Becker driver with the same results: (dmesg output from latest Donald Becker driver) 3c59x.c:v0.99X 6/21/2002 Donald Becker, becker@scyld.com http://www.scyld.com/network/vortex.html eth0: 3Com 3c905C Tornado at 0xe000, 00:01:03:de:57:37, IRQ 7 8K buffer 5:3 Rx:Tx split, autoselect/Autonegotiate interface. MII transceiver found at address 24, status 782d. Using bus-master transmits and whole-frame receives.
