Update the 18xx FW status private part to include Tx related link priorities. Introduce new HW ops to determine link priority per chip family. For 18xx the changes are: - Suspended links are at most low priority and Tx for them is stopped beyond the suspend threshold. - Active links now get their thresholds directly from FW - There's a new "stop" threshold for active links, at which point a link stops receiving new packets. Update the min 18xx FW version required to make sure suspended links bitmap is advertised by the FW. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
