Description:      Roadmap release

Additional configuration options related to PTP/HSR (redbox)

The mesa_acl_ptp_action_conf_t and mesa_ts_operation_mode_t structures have
been extended with additional fields to control how PTP frames are processed.

Additional MAC-tables configuration to support TC11

The mesa_learn_mode_t type has been extended with a one_shot and
learn_limit fields. The one_shot mode ensures that a learned entry cannot
move to a different port, and lean_limit puts a budget on how many entries can
be learned on a given port.

Both features are added to support TC11.

Support of in-band time-stamping via preamble (PHC)

The mesa_ts_operation_mode_t structure has been extended with additional
fields to support in-band timestamping. This feature requires a PHY supporting
PCH as well.

Support of HSR/Mode U

The mesa_rb_conf_t structure has been extended with flag to support Mode U.

Mode U enabled means:

If a unicast frame arrives on an LRE port and the DMAC of the frame is in the
PNT, forward it to the other LRE port (as well as to the interlink port).

If Mode U is disabled, such a frame will only be forwarded to the interlink
port.

This overcomes issues where it can take up to PNT timeout (60 seconds by
default) for frames to come through again if certain links are broken.
