This causes the code to truncate the values greater than 255 to 255 or less when calling ice_aq_program_acl_entry() resulting in the wrong TCAM index being programmed for the specified rule. The result is that the rule action doesn't work correctly (packets don't get routed to the correct queue or dropped if that is the action). Fix the issue by changing the variable to be a u16 again.
