Yes.  Unresolved issues:
   One report of a system where the '562 EEPROM configuration info could
   not be read.

Yes.  It's the same as a rtl8139C chip.

Correct.  The very new 8139C+ has very interesting performance features,
but the existing 8139C is significantly less efficient than the eepro100.

For both chips we ship my drivers, with the Intel's e100 driver listed as
an acceptable alternative for the eepro100.
