Subject: [PATCH] ifcfg/write-ifcfg.sh: bind bond and bridge interfaces to HW
|
|
|
83bbb1 |
|
|
|
83bbb1 |
either by s390 SUBCHANNELS or HWADDR, if the interface name is not
|
|
|
83bbb1 |
persistent.
|
|
|
83bbb1 |
|
|
|
83bbb1 |
Previously, this was bound unconditionally with HWADDR.
|
|
|
83bbb1 |
|
|
|
83bbb1 |
(cherry picked from commit 80043e21c16db168ad087a162f1fa97cae866c8d)
