net: ethernet: freescale: set FEC ethtool regs version
Currently the ethtool_regs version is set to 0 for FEC devices. Use this field to store the register dump version exposed by the kernel. The choosen version 2 corresponds to the kernel compile test: #if defined(CONFIG_M523x) || defined(CONFIG_M527x) || defined(CONFIG_M528x) || defined(CONFIG_M520x) || defined(CONFIG_M532x) || defined(CONFIG_ARM) || defined(CONFIG_ARM64) || defined(CONFIG_COMPILE_TEST) and version 1 corresponds to the opposite. Binaries of ethtool unaware of this version will dump the whole set as usual. Signed-off-by: Vivien Didelot <vivien.didelot@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
