...djust drivers that support the 'FLOW_DISSECTOR_KEY_META' key to reject filters that try to match on the newly added layer 2 miss option. Add an extack message to clearly communicate the failure reason to user space. Example: # tc filter add dev swp1 egress pref 1 proto all flower skip_sw l2_miss true action drop Error: mlxsw_spectrum: Can't match on "l2_miss".

...isting metadata options such as 'indev'. A bit that is set for every flooded packet would also work, but it does not allow us to differentiate between registered and unregistered multicast traffic which might be useful in the future. A relatively generic name is chosen for this bit - 'l2_miss' - to allow its use to be extended to other layer 2 devices such as VXLAN, should a use case arise. With the above, the control plane can implement a non-DF filter using the following tc filters: # tc filter add dev bond0 egress pref 1 proto all flower indev vxlan0 dst_mac 01:00:00:00:00:00/...

Greeting All I have create a pool that consists oh a hard disk and a ssd as a cache zpool create hdd c11t0d0p3 zpool add hdd cache c8t0d0p0 - cache device I ran an OLTP bench mark to emulate a DMBS One I ran the benchmark, the pool started create the database file on the ssd cache device ??????????? can any one explain why this happening ? is not L2ARC is used to absorb the evicted data
