mac-address

Error Handling

• If the config file corrupts, NO MAC address would be generated.
• If the FRU data corrupts, use random MAC addresses instead.

Find FRU automatically

The scripts/find-fru-bus.sh can find specified FRU according to the eeprom in config.txt. This script gets back FRU's bus number as well as address and update to config.txt.

Config File Format

The config file is in /usr/share/mac-address/config.txt.

The followings are items needed for the config file.

• eeprom: This is the node name(of_node/name) of FUR's EEPROM.
• fruBusNum: This is the i2c bus number of FRU that stores MAC address info.
• fruAddr: This is FRU address that stores MAC address info.
• numberMac: This represents the number of MAC addresses.
• mac<number>: This contains MAC address name.

Note that usb0_dev and usb0_host are for USB ports.

Here is an example.

eeprom=fru_1
fruBusNum=1
fruAddr=0x01
numberMac=4
mac1=eth0
mac2=eth1
mac3=usb0_dev
mac4=usb0_host
