CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and
decrypt packets at MAC level. This block is a global resource
with hardware resources like SecYs, SCs and SAs and is in
between NIX block and RPM LMAC. CN10K-B silicon has only one MCS
block which receives packets from all LMACS whereas CNF10K-B has
seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. Those
differences between IPs are handled using separate ops.
This patch adds basic driver and does the initial hardware
calibration and parser configuration.
