This patchset introduces support for offloading TC cls_flower and actions
to Spectrum TCAM-base policy engine.
The patchset contains patches to allow work with flexible keys and actions
which are used in Spectrum TCAM.
It also contains in-driver infrastructure for offloading TC rules to TCAM HW.
The TCAM management code is simple and limited for now. It is going to be
extended as a follow-up work.
The last patch uses the previously introduced infra to allow to implement
cls_flower offloading. Initially, only limited set of match-keys and only
a drop and forward actions are supported.
As a dependency, this patchset introduces parman - priority array
area manager - as a library.
