tc: Reflect HW offload status
|
|
|
36cfb7 |
|
|
|
36cfb7 |
Currently there is no way of querying whether a filter is
|
|
|
36cfb7 |
offloaded to HW or not when using "both" policy (where none
|
|
|
36cfb7 |
of skip_sw or skip_hw flags are set by user-space).
|
|
|
36cfb7 |
|
|
|
36cfb7 |
Add two new flags, "in hw" and "not in hw" such that user
|
|
|
36cfb7 |
space can determine if a filter is actually offloaded to
|
|
|
36cfb7 |
hw or not. The "in hw" UAPI semantics was chosen so it's
|
|
|
36cfb7 |
similar to the "skip hw" flag logic.
|
|
|
36cfb7 |
|
|
|
36cfb7 |
If none of these two flags are set, this signals running
|
|
|
36cfb7 |
over older kernel.
