Support single ingress pool for MSFT SKUs and optimize headroom calcu…
…lation (#4686) Calculate pool size in t1 as 24 * downlink port + 8 * uplink port - Take both port and peer MTU into account when calculating headroom - Worst case factor is decreased to 50% - Mellanox-SN2700-C28D8 t0, assume 48 * 50G/5m + 8 * 100G/40m ports - Mellanox-SN2700 (C32) - t0: 16 * 100G/5m + 16 * 100G/40m - t1: 16 * 100G/40m + 16 * 100G/300m Signed-off-by: Stephen Sun <stephens@mellanox.com> Co-authored-by: Stephen Sun <stephens@mellanox.com>
