[gPXE] [gPXE-devel] New tg3 driver - Call for testers

Thu Jan 26 07:21:00 EST 2012

Hi Thomas,

I have started testing your code on a HP Z800 Workstation.  The network
card is listed under Linux as "Broadcom Corporation NetXtreme BCM5764M
Gigabit Ethernet PCIe (rev 10)" (14e4:1684).
The latest code i got by doing a "git clone -b tg3 git://
git.etherboot.org/people/meteger/gpxe.git". If I use the following make
line: make clean ; make -j 10 DEBUG=tg3_main,tg3_hw,tg3_phy
EMBEDDED_IMAGE=~/disk-images/tftp.gpxe   ,then I get the following output:
----------------------------------------------------
Link is down
ok

gPXE 1.0.1+ -- Open Source Boot Firmware -- http://etherboot.org
Features: AoE HTTP iSCSI DNS TFTP bzImage COMBOOT ELF Multiboot PXE PXEXT

Link is down
Waiting for link-up on net0...Link is up at 1000 Mbps, full duplex
Flow control is off for TX and off for RX
 ok
DHCP (net0 00:1f:29:05:2b:9a)................ Connection timed out
(0x4c106035)
Could not configure net0: Connection timed out (0x4c106035)
Could not configure any interface.

--------------------------------------------------------

To me it looks like packet loss but Linux has no problems with the card at
the 2.6.38 kernel level.
Is there any debug options I can use to get more info?

btw, if you didn't get my mail earlier, the embedded script problem I had
earlier was caused by a missing "#!gpxe" header.  Without it, the script is
not recognized.

Quinn Plattel
