You got that backwards. b353b241f1eb renamed `adapter` to `fep` to align
it with the rest of the driver. I decided to amend the revert to keep this renaming.
`adapter` was introduced in 6605b73 when `fec_ptp.c` was created.

Here you can clearly see the nature of my amend. I thought I added this to the commit message,
but it seems I have forgot.
