thanks for your input. No, the interface is configured in a very
straightforward way without any bells and whistles. It has a four IPv4
addresses, plus one auto-generated IPv6 address (link layer local).
I don't use briding and didn't enable multicast in /etc/sysctl.conf,
either.
There are also no processes specifically using this interface (ie, no
tcpdump or similar). This is the whole process list:

None of these suggests to me that ALLMULTI or PROMISC should be on,
and ifconfig's man page doesn't suggest that I can easily turn
them off.
If you have any suggestions about how to debug this, I'm all ears.
TIA!
Kind regards,
