Subject: net: sched: add tcf_proto_op to offload a rule
Patch-mainline: v4.19-rc1
Git-commit: e56185c78b500ac4d08768278ad8a25d5b756942
References: bsc#1109837

Create a new tcf_proto_op called 'reoffload' that generates a new offload
message for each node in a tcf_proto. Pointers to the tcf_proto and
whether the offload request is to add or delete the node are included.
Also included is a callback function to send the offload message to and
the option of priv data to go with the cb.
