This is a duplication of the FP adminStatus logic introduced for tc-mqprio. Offloading is done through the tc_mqprio_qopt_offload structure embedded within tc_taprio_qopt_offload. So practically, if a device driver is written to treat the mqprio portion of taprio just like standalone mqprio, it gets unified handling of frame preemption. I would have reused more code with taprio, but this is mostly netlink attribute parsing, which is hard to transform into generic code without having something that stinks as a result. We have the same variables with the same semantics, just different nlattr type values (TCA_MQPRIO_TC_ENTRY=5 vs TCA_TAPRIO_ATTR_TC_ENTRY=12; TCA_MQPRIO_TC_ENTRY_FP=2 vs TCA_TAPRIO_TC_ENTRY_FP=3, etc) and consequently, different policies for the nest. Every time nla_parse_nested() is called, an on-stack table "tb" of nlattr pointers is allocated statically, up to the maximum understood nlattr type. That array size is hardcoded as a constant, but when transforming this into a common parsing function, it would become either a VLA (which the Linux kernel rightfully doesn't like) or a call to the allocator. Having FP adminStatus in tc-taprio can be seen as addressing the 802.1Q Annex S.3 "Scheduling and preemption used in combination, no HOLD/RELEASE" and S.4 "Scheduling and preemption used in combination with HOLD/RELEASE" use cases. HOLD and RELEASE events are emitted towards the underlying MAC Merge layer when the schedule hits a Set-And-Hold-MAC or a Set-And-Release-MAC gate operation. So within the tc-taprio UAPI space, one can distinguish between the 2 use cases by choosing whether to use the TC_TAPRIO_CMD_SET_AND_HOLD and TC_TAPRIO_CMD_SET_AND_RELEASE gate operations within the schedule, or just TC_TAPRIO_CMD_SET_GATES. A small part of the change is dedicated to refactoring the max_sdu nlattr parsing to put all logic under the "if" that tests for presence of that nlattr.

/* "Handles"
|
|
---------
|
|
|
|
All the traffic control objects have 32bit identifiers, or "handles".
|
|
|
|
They can be considered as opaque numbers from user API viewpoint,
|
|
but actually they always consist of two fields: major and
|
|
minor numbers, which are interpreted by kernel specially,
|
|
that may be used by applications, though not recommended.
|
|
|
|
F.e. qdisc handles always have minor number equal to zero,
|
|
classes (or flows) have major equal to parent qdisc major, and
|
|
minor uniquely identifying class inside qdisc.
|
|
|
|
