Subject: [PATCH] bonding: use hwaddr of the slave rather than the master
83bbb1
83bbb1
When a bonded interface is brought up, any slaves included in the bond
83bbb1
have their hardware address set to that of the bond master.  Although
83bbb1
this allows an interface to be brought up on start up, when the
83bbb1
configuration file is imported into the booted system it prevents
83bbb1
the bonded interface being successfully restarted.
83bbb1
83bbb1
The fix involves obtaining the hardware address of the slaves before
83bbb1
they are added to the bond and then using this value in the
83bbb1
configuration file.

(cherry picked from commit 83c9ff7dbb465bedb10119bb2883d34266922180)
