Hi Tim,

When accessing PHY registers it is often desirable to only update selected bits, so it is necessary to first read the current value before writing back an modified value with the relevant bits updated.
To simplify this and to allow such operations to be incorporated into simple shell scripts propose adding a 'modify' option to the existing mii command, which takes a mask indicating the bits to be updated in addition to a data value containing the new bits, ie, <updated> = (<data> & <mask>) | (<current> & ~<mask>).
