Log Message:
-----------
dpif-netdev: Don't use zero flow mark.
Zero flow mark is used to indicate the HW to remove the mark. A packet
marked with zero mark is received in SW without a mark at all, so it
cannot be used as a valid mark. Change the pool range to fix it.

Log Message:
-----------
netdev-offload-dpdk: Fix Ethernet matching for type only.
For OVS rule of the form "eth type is 0x1234 / end", rule is offloaded
in the form of "eth / end", which is incorrect. Fix it.

Log Message:

dpif-netdev: Add check mark to avoid ovs-vswitchd crash.
When changing the pmd interfaces attribute, ovs-vswitchd will
reload pmd and flush offload flows. reload_affected_pmds may
be invoked twice or more. In that case, the flows may been
queued to "dp_netdev_flow_offload" thread again.
For example:
$ ovs-vsctl -- set interface <Interface> options:dpdk-lsc-interrupt=true
ovs-vswitchd main flow-offload thread
append F to queue ...
...
append F to queue
... del F
... del F (crash [1])

Log Message:
-----------
dpif-netdev: Return error code when no mark available.
The max number of mark is (UINT32_MAX - 1), that is
enough to be used. But theoretically, if there are no
mark available, the later different flows will shared
the mark INVALID_FLOW_MARK, that may break the function.
If there are no available mark to be used, return error
code.
