Aug 22, 2008 For my LAN (Internet), I am currently working with the Intel Pro 100 VE driver found on the Uphuck disc, which is meant for Intel 8255x chipsets. Msi digivox mini hybrid driver for mac. Its working OK on my 82540EM LAN chipset, but there is a tiny random issue where the Ethernet sort.
I was trying to write a pci driver which can display the MAC address of my Ethernet card.Running a Ubuntu on VM and my Ethernet card is Intel one as follows00:08.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)
I was able to get the data sheet of the same from Intel website and as per data sheet it says IO address are mapped to Bar 2 (Refer to pg 87) and MAC can be read using RAL/RAH register which are at offset RAL (05400h + 8*n; R/W) and RAH (05404h + 8n; R/W)2 18h IO Register Base Address (bits 31:2) 0b mem
Based on this information, i wrote a small PCI driver but i always get the MAC as fff and when i debugged further, i see io_base address is always zero.
Below is the code
lspci -x output of my card00:08.0 Ethernet controller: Intel Corporation 82540EM Gigabit Ethernet Controller (rev 02)00: 86 80 0e 10 07 00 30 02 02 00 00 02 00 40 00 0010: 00 00 82 f0 00 00 00 00 41 d2 00 00 00 00 00 0020: 00 00 00 00 00 00 00 00 00 00 00 00 86 80 1e 0030: 00 00 00 00 dc 00 00 00 00 00 00 00 09 01 ff 00
Can any one let me know what am i doing wrong?

I've modified your code and commented on changes. I have removed all of your existing comments to avoid confusion, and have only modified your probe function.
You will need to add a corresponding call to iounmap() in your device_remove() routine. Take a look at the Intel E100E driver source code for some good examples.
