Re: [PATCH v2 net-next 00/10] DSA FDB isolation

Hello:

This series was applied to netdev/net-next.git (master)
by David S. Miller [off-list ref]:

There are use cases which need FDB isolation between standalone ports
and bridged ports, as well as isolation between ports of different
bridges. Most of these use cases are a result of the fact that packets
can now be partially forwarded by the software bridge, so one port might
need to send a packet to the CPU but its FDB lookup will see that it can
forward it directly to a bridge port where that packet was autonomously
learned. So the source port will attempt to shortcircuit the CPU and
forward autonomously, which it can't due to the forwarding isolation we
have in place. So we will have packet drops instead of proper operation.
