4 Subject: [PATCH 002/145] net: ethernet: ti: cpsw: unsync mcast entries while
5 switch promisc mode
6
7 [ Upstream commit 9737cc99dd14b5b8b9d267618a6061feade8ea68 ]
8
9 After flushing all mcast entries from the table, the ones contained in
10 mc list of ndev are not restored when promisc mode is toggled off,
11 because they are considered as synched with ALE, thus, in order to
12 restore them after promisc mode - reset syncing info. This fix
13 touches only switch mode devices, including single port boards
14 like Beagle Bone.
