Description of problem:
"lsmod" showed tg3 was loaded and usage count was 0.
The nic is "Ethernet controller Broadcom Co. NetXtreme BCM 5751 Gigabit Ethernet PCI Express" intergrated on a Dell GX280".
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Do a fresh install of FC3
2.configure the network eth0 use dhcp
4.verify network is working,
Actual Results: 5."lsmod" shows "tg3 79045 0"
the usage count is 0
Expected Results: expected to be >=1
since the usage count is 0, I can "rmmod tg3" to remove the module
and the network stoping working (and eth0 will no longer show up with "ifconfig -a").
Is this a bug, or a new feature of this driver?
its by design. all network drivers in 2.6 do this.
