With the patch below the first message becomes
e1000e 0000:01:00.0: Warning: detected DSPD enabled in EEPROM
which makes it similar to directly preceding messages.

I'm still wondering about this...
Same goes for the "warning" about ASPM.

Use dev_warn instead of e_warn in e1000_eeprom_checks() as the
interface name has not yet been assigned at that point.
