![Alexander Duyck](/assets/img/avatar_default.png)
This patch is meant to allow for support of multiple hardware offload type for a single device. There is currently no bounds checking for the hw member of the mqprio_qopt structure. This results in us being able to pass values from 1 to 255 with all being treated the same. On retreiving the value it is returned as 1 for anything 1 or greater being set. With this change we are currently adding limited bounds checking by defining an enum and using those values to limit the reported hardware offloads.

/* "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.
|
|
|
|
