[Mellanox] Update the buffer setting (#4989)
* Update the buffer size based on the latest excel Signed-off-by: Stephen Sun <[email protected]> * Align the buffer configuration with the latest formula: - reduce redundant "*2" in formula - use port MTU for local sending the PFC frame and peer lossless MTU for peer sending lossless traffic Buffer pool size updated accordingly. Signed-off-by: Stephen Sun <[email protected]>
