net/mlx5e: Receive buffer configuration
Add APIs for buffer configuration based on the changes in pfc configuration, cable len, buffer size configuration, and priority to buffer mapping. Note that the xoff fomula is as below xoff = ((301+2.16 * len [m]) * speed [Gbps] + 2.72 MTU [B] xoff_threshold = buffer_size - xoff xon_threshold = xoff_threshold - MTU Signed-off-by: NHuy Nguyen <huyn@mellanox.com> Reviewed-by: NParav Pandit <parav@mellanox.com> Signed-off-by: NSaeed Mahameed <saeedm@mellanox.com>
