[PATCH RFC net-next v6 01/15] net: driver: stmmac: Fix CSR divider comment

From: "Jan Petrous (OSS)" <jan.petrous at oss.nxp.com>

The comment in declaration of STMMAC_CSR_250_300M
incorrectly describes the constant as '/* MDC = clk_scr_i/122 */'
but the DWC Ether QOS Handbook version 5.20a says it is
CSR clock/124.
