[Qemu-devel] Re: [PATCH][RFC] qemu:virtio-net: Use TUNSETTXFILTER for MAC filteringlogin register about

[Dragos Tatulea]

I'd like to pick up this patch and rework it based on your
suggestions. Need it for [1]. Most opinions seem to be pointing to a
generic software mac filtering in the VLAN layer with hw support if
necessary. Here's what I had in mind:
- For the generic mac filtering we can use something similar to
VirtIONet's mac_table.
- Make receive_filter a callback in NetClientInfo. NIC's that don't
support filtering can use a generic_receive_filter based on the mac
table (but should be turned off by default).
- For hw filtering support I'm not sure how to validate the
"interesting" setup with a tap/macvtap and virtio-net on top of it.
- Of course, this needs to be documented as "best effort" filtering.
Just like the virtio-net mac table.

Please give me your feedback. Thanks.
