This is where it got tricky for me, I thought I would find a .c file like e1000e.c or e1000e_main.c as was shown in the VM example(I'm using native Linux) but I can see in the subdirectory are .o files that I can't modify. And I don't what to do or how to find the probe function I'm supposed to modify

Hello,
Are you saying you do not have any .c files under the
drivers/net/ethernet/intel/e1000e/ directory?

On my machine, I see the following on trying to locate the probe function of
this driver:

	drv@runicha:~/git/kernels/linux-next$ grep 'probe(' drivers/net/ethernet/intel/e1000e/*.c
	drivers/net/ethernet/intel/e1000e/netdev.c:static int e1000_probe(struct pci_dev *pdev, const struct pci_device_id *ent)

Can you check if you see something similar?

Thanks,
Deepak.
