>Description:
My host's onboard ethernet, provided by ale(4), appears unable to receive IPv6 multicast packets, including solicited or unsolicited router advertisements, unless the interface is in promiscuous mode. Running "tcpdump icmp6" will show such packets being received, and when an RA is received with no default inet6 route installed, the routing table will be updated to include a default route. When tcpdump is not running or is running with the '-p' flag to avoid promiscuous mode, the only v6 multicasts seen are those generated by the host. An outgoing router solicitation can be seen, but no response is detected. Other hosts on this LAN, including a FreeBSD 8.0-BETA4/i386 VirtualBox with emulated em(4) (bridged by VirtualBox/OpenSolaris, no NAT), do not experience this problem.
('ifconfig ale0 promisc' also allows multicasts to be received, of course.)

>How-To-Repeat:
Install FreeBSD 8 on a host with the following network adapter connected to an IPv6-enabled network:
ale0@pci0:2:0:0: class=0x020000 card=0x831c1043 chip=0x10261969 rev=0xb0 hdr=0x00
vendor = 'Attansic (Now owned by Atheros)'
device = 'PCI-E ETHERNET CONTROLLER (AR8121/AR8113 )'
class = network
subclass = ethernet
(I cannot speak to whether other chipsets supported by this driver are similarly affected.)
As above, run tcpdump(1) with and without the -p flag while soliciting router advertisements ('rtsol aleX', where 'X' is the appropriate interface instance). Verify that no router advertisements are seen by 'tcpdump -p'; verify, such as with netstat(1), that the routing table is not updated when no default inet6 route exists and 'tcpdump -p' is running.
