The 2924 is a Cisco switch. Since we have had problems in the past with the switch and servers negotiating the wrong speeds we have gone to forcing both of them to 100 full duplex. So I would like to be able to force the tg3 nics in the Compaq DL360 to full duplex on boot.
Here is the output from lspci -v
01:05.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5701 Gigabit Ethernet (rev 15)
Subsystem: Compaq Computer Corporation NC7780 Gigabit Server Adapter (embedded, WOL)
Flags: bus master, 66Mhz, medium devsel, latency 64, IRQ 5
Memory at f7fb0000 (64-bit, non-prefetchable) [size=64K]

Capabilities: [48] Power Management version 2
Capabilities: [50] Vital Product Data
Capabilities: [58] Message Signalled Interrupts: 64bit+ Queue=0/3 Enable-
The odd thing is I am forcing the switch to full duplex and when I reboot the server it still comes up in half duplex mode?
Here is the output from modinfo tg3

I hope this helps, let me know if there is anything else you need.

Can you tell me which Broadcom adapters do you have? Why are you
forcing speed and duplex? If you force on the NIC side you must force on
the switch side, otherwise you would get duplex mismatch. What kind of
switch is 2924? What version of bcm5700 driver are you using?

Subject: Compaq DL360 G2 TG3 Duplex Issue
I read the following issue with the NIC is these servers.
https://listman.redhat.com/pipermail/broadcom-list/2003-January/000006.h
tml But this solution did not seem to help my server, to boot into full
duplex mode. I have 20 of them connected to a 2924 with all the ports
forced to full duplex 100, so that there can be no confusion.
Yet these servers all still come up in 100 half duplex mode. I
was hoping someone could shed some light on this issue. Let me know if
there is any other information you guys would like to see from me to fix
this.
