Add initialization to the if_ie driver for the Micom Interlan NI5210 card.
This is a very old 82586 based card with only 8Kb or 16Kb on board memory.
Also only 8-bit wide instead of 16-bit like the AT& or 3COM card.
Warning: this thing is only tested so far that it detects all bits
correctly but is not yet on an ethernet. Will do that tomorrow.
