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

The matchall classifier matches every packet and allows the user to apply
actions on it. In addition, it supports the skip_sw and skip_hw (as can
be found on u32 and flower filter) that direct the kernel to skip the
software/hardware processing of the actions.
This filter is very useful in usecases where every packet should be
matched. For example, packet mirroring (SPAN) can be setup very easily
using that filter.
