In doing so, P0_REFCLK_SEL was set to "pcs_mac_clk_divx1_ln_0" (0x3) and P0_STANDARD_MODE was set to LANE_MODE_GEN1, which results in a data rate of 5.15625 Gbps. However, since the USXGMII mode can support up to 10.3125 Gbps data rate, the aforementioned fields should be set to "pcs_mac_clk_divx0_ln_0" (0x2) and LANE_MODE_GEN2 respectively. Fix the configuration accordingly to truly support USXGMII up to 10G.
