How to make first i210 port to be dedicated IPMI port?

Purpose:

The article is for fulfilling specific user application. After this modification, user will not be able to find i210 port (bus 02:00.0) under OS, but keep IPMI (nc-si) workable.

Please note, this modification only be valid for the i210 firmware later than 2.0.

# lspci -s 02:00.0 -vvv | grep V2
[V2] Vendor specific: V2.00.00

Target Audience:

FWA-3050 users.

Instruction Step:

(disable i210 via PCA9554 via IO controller)

1. Set PCA9554 IO1 as output

# ipmitool i2c bus=2 0x4e 0 0x03 0xfd

2. Set PCA9554 IO1 low level

# ipmitool i2c bus=2 0x4e 0 0x01 0xfd

3. x86 reboot

# reboot

4. Check 1st i210 (bus 02:00.0) not under host OS

# lspci | grep -i eth

###SIDE EFFECT###

The workaround could cause PXE boot options missing in BIOS if BIOS in incompatible version. Please contact your Advantech representative for further assistance.

###FOLLOWING CONDITION WILL MAKE THE MODIFICATION INVALID###

1. BMC or Bootloader firmware upgrade

2. Manually set value back 

Step 1. Set PCA9554 IO1 as output

# ipmitool i2c bus=2 0x4e 0 0x03 0xfd

Step 2. Set PCA9554 IO1 high level

# ipmitool i2c bus=2 0x4e 0 0x01 0xff

Step 3. x86 reboot

# reboot

Step 4. Check 1st i210 port back under host OS

# lspci | grep -i eth
