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. |
| 15 |

Fixes: commit 5da1948969bc |
