This broke rocker, since rocker didn't have a hardware (or software) mechanism for ageing out its learned FDB entries. This patchset reintroduces Siva's bridge driver patch to skip externally added entries and adds support in rocker so rocker can age out its own entries. Rocker does this using a software timer similar to the bridge's FDB garbage collection timer. Other switchdev devices/drivers can use this software timer method or program the device to nofity aged-out entries to the driver. Updated switchdev.txt documentation to reflect current state-of-the-art. This removes one more XXX todo comment in switchdev.txt. Scott Feldman (6): rocker: track when FDB entry is touched. rocker: store rocker_port in fdb key rather than pport rocker: adding port ageing_time for ageing out FDB entries bridge: define some min/max ageing time constants we'll use next rocker: add FDB cleanup timer switchdev: update documentation on FDB ageing_time Siva Mannem (1): bridge: don't age externally added FDB entries Documentation/networking/switchdev.txt | 24 +++++------ drivers/net/ethernet/rocker/rocker.c | 69 +++++++++++++++++++++++++++----- include/linux/if_bridge.h | 4 ++ net/bridge/br_fdb.c | 2 + 4 files changed, 77 insertions(+), 22 deletions(-) -- 1.7.10.4
