Subject: Re: [PATCH net-next v3] net: bridge: Fix improper taking over HW
 learned FDB

> Commit 7e26bf45e4cb ("net: bridge: allow SW learn to take over HW fdb
> entries") added the ability to "take over an entry which was previously
> learned via HW when it shows up from a SW port".
> 
> However, if an entry was learned via HW and then a control packet
> (e.g., ARP request) was trapped to the CPU, the bridge driver will
> update the entry and remove the externally learned flag, although the
> entry is still present in HW. Instead, only clear the externally learned
> flag in case of roaming.
