Geert Uytterhoeven a14c7d15ca sh_eth: Fix lost MAC address on kexec ... Commit 740c7f31c0 ("sh_eth: Ensure DMA engines are stopped before freeing buffers") added a call to sh_eth_reset() to the sh_eth_set_ringparam() and sh_eth_close() paths. However, setting the software reset bit(s) in the EDMR register resets the MAC Address Registers to zero. Hence after kexec, the new kernel doesn't detect a valid MAC address and assigns a random MAC address, breaking DHCP. Set the MAC address again after the reset in sh_eth_dev_exit() to fix this. Tested on r8a7740/armadillo (GETHER) and r8a7791/koelsch (FAST_RCAR).
