RE: Download speed
Test done on two machine (HP 8000 Elite with Intel 82567lm-3 and HP 8300 Elite with Intel 82579lm), using an HP 8200 Elite as DHCP/TFTP/HTTP server.
We have currently no PCI/PCIe card for loopback test.
Results:
Both cards are succesful on all test (don't know for loopback).
ifstat command throw errors (but still show link status) on both card : 3c086003, 440e6003 and 380f6001

Speedresults:
- HP 8000 Elite with Intel 82567lm-3 and a 512Mb file => Between 5.3s to 15.8s, using more than 90% bandwidth used.
- HP 8300 Elite with Intel 82579lm and a 8Mb file => Alltime 7.2s with 100% bandwidth used.

We have done one another test using direct link on 82579lm :
- Forcing 100Mb Full Duplex => Speed is now correct, 100% of 100Mb is used.
- Forcing 1Gb Full Duplex => During iPXE booting, the link go down and never go up again...
Setting back to negociate the speed is always 10Mb in iPXE.

I hope this results may help finding a solution...
Yes, It's auto-negociation issue. I wil try tomorrow with a 100Mb hub. All tests are done with Intel card, no broadcom (We only have rare old computer using broadcom card).

Are there more test we could do to help?
