net: stmmac: fix CBS idleslope and sendslope calculation
[ Upstream commit 2487768 ] When link speed is not 100 Mbps, port transmit rate and speed divider are set to 8 and 1000000 respectively. These values are incorrect for CBS idleslope and sendslope HW values calculation if the link speed is not 1 Gbps. This patch adds switch statement to set the values of port transmit rate and speed divider for 10 Gbps, 5 Gbps, 2.5 Gbps, 1 Gbps, and 100 Mbps. Note that CBS is not supported at 10 Mbps.
