Commit Message

Previously, shared blocks were only relevant for the pseudo-qdiscs ingress
and clsact. Recently, a qevent facility was introduced, which allows to
bind blocks to well-defined slots of a qdisc instance. RED in particular
got two qevents: early_drop and mark. Drivers that wish to offload these
blocks will be sent the usual notification, and need to know which qdisc it
is related to.

To that end, extend flow_block_offload with a "sch" pointer, and initialize
as appropriate. This prompts changes in the indirect block facility, which
now tracks the scheduler in addition to the netdevice. Update signatures of
several functions similarly.

Notes:
    v2:
    - In struct flow_block_indr, track both sch and dev.

nit: the number of arguments is getting out of hand here, perhaps it's
     time to pass a structure in.

I would say that adding a distinctly-typed and distinctly-named argument
does not make the other arguments less clear, or increase the risk of
mixing them up in a way that the compiler would not catch.

Taken from another angle, the argument list is not passed through layers
of other functions, so the structure would be assembled in
bnxt_tc_setup_indr_block() and then unpacked again in
flow_indr_block_cb_alloc(). Nothing is saved in that regard either.

Also, flow_indr_block_cb_alloc() is a simple function. When a structure
needs to be introduced to carry the arguments, it might be more
straightforward to just open-code it.
