+Ifconfig uses obsolete kernel interface.

626e1f7 |
+It uses the ioctl access method to get the full address information,
|
|
|
626e1f7 |
+which limits hardware addresses to 8 bytes.
|
|
|
626e1f7 |
+Since an Infiniband address is 20 bytes,
|
|
|
626e1f7 |
+only the first 8 bytes of Infiniband address are displayed.
