Hello,

this series seems to be based on slightly different version of the kernel
counterpart than what was merged into mainline. One difference I noticed is
that this series uses ETHTOOL_A_MODULE_FW_FLASH_PASS while kernel headers
use ETHTOOL_A_MODULE_FW_FLASH_PASSWORD; but I'm not sure if it's the only
difference.

Could you please check it and update what is needed?

Michal
