Merge branch 'net-tc-indirect-block-relay'

John Hurley says:

====================
Ensure egress un/bind are relayed with indirect blocks

On register and unregister for indirect blocks, a command is called that
sends a bind/unbind event to the registering driver. This command assumes
that the bind to indirect block will be on ingress. However, drivers such
as NFP have allowed binding to clsact qdiscs as well as ingress qdiscs
from mainline Linux 5.2. A clsact qdisc binds to an ingress and an egress
block.

Rather than assuming that an indirect bind is always ingress, modify the
function names to remove the ingress tag (patch 1). In cls_api, which is
used by NFP to offload TC flower, generate bind/unbind message for both
ingress and egress blocks on the event of indirectly
registering/unregistering from that block. Doing so mimics the behaviour
of both ingress and clsact qdiscs on initialise and destroy.

This now ensures that drivers such as NFP receive the correct binder type
for the indirect block registration.
