Subject: [PATCH net-next 01/13] net: sched: Pass qdisc reference in struct flow_block_offload
From: Petr Machata <petrm@...lanox.com>
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 instead of the netdevice. Update signatures of
several functions similarly. Deduce the device from the scheduler when
necessary.
