In ether82563.c, there are some definitions like:
Tdbal = 0x3800, /* Tdesc Base Address Low */
Tdbah = 0x3804, /* Tdesc Base Address High */
Tdlen = 0x3808, /* Descriptor Length */
Tdh = 0x3810, /* Descriptor Head */
Tdt = 0x3818, /* Descriptor Tail */
.
I searched its document around, but failed.
I can fine a document which describes parts of it.
If you know it, please teach me where is it.

PS: I searched i219 drivers, and found only 9front has workable it.
However, it uses pcienable() etc.
