rtl8139 errors

[huevo5050]

Hi I have this card: http://www.ovislink-espana.com/index.php...VO-8139ITX

with a chipset RTL8139D.

Then when I'm trying to boot PXE from this fails with connection timed out. Them, in CLI, i can see with ifstat command the following errors:

[RXE: 7 x "operation not supported (http://ipxe.org/3c086003)"]
[RXE: 1 x "Error 0x440e6003 (http://ipxe.org/440e6003)"]

I'm using a daily build of iPXE booting from USB. This USB in other chipset/cards works well.

Another clue. When I'm repeat the process with the former gPXE 1.0.1 and the ethernet cable is plugged boot complain with "gPXE initialising devices" if the cable is unplugged gPXE boots well.

Can I solve this issue. Can i help you to debug that? Thanks in advance and apologize my poor poor english.
