Subject: [PATCH] bonding: use hwaddr of the slave rather than the master
|
|
|
18971c |
|
|
|
18971c |
When a bonded interface is brought up, any slaves included in the bond
|
|
|
18971c |
have their hardware address set to that of the bond master. Although
|
|
|
18971c |
this allows an interface to be brought up on start up, when the
|
|
|
18971c |
configuration file is imported into the booted system it prevents
|
|
|
18971c |
the bonded interface being successfully restarted.
|
|
|
18971c |
|
|
|
18971c |
The fix involves obtaining the hardware address of the slaves before
|
|
|
18971c |
they are added to the bond and then using this value in the
|
|
|
18971c |
configuration file.
|
|
|

|
|
|
18971c |
(cherry picked from commit 83c9ff7dbb465bedb10119bb2883d34266922180)
