Hi,
currently, the userspace is informed about the port the MAC is learned
on a bridge and about the bridge removing the MAC from its forwarding
table, but not when the MAC is learned on a different port. This is
inconsistent and makes it difficult for applications to keep track of
all MACs learned by a bridge on a subset of its ports.
Please find attached a patch that fixes this by sending an RTM_NEWNEIGH
message when the forwarding destination port changes.
Regards,
M. Braun
