Subject: [PATCH v2 09/12] net/ice/base: change fdir desc preparation
Change internal implemenatation of how FD filter programming desc is prepared.
This is to minimize the amount of code needed to prep the FD filter programming
desc (avoid memcpy, etc...) and just use predefined shifts and mask. This type
of change are needed to expedite FD setup during data path (ADQ uses this
codepath during initial flow setup) and it will also be useful when adding
side-band flow-director filter.
