Subject: [PATCH 10/14] tests: make lsns-netnsid portable
|
|
|
cbc4cf |
|
|
|
cbc4cf |
It seems ip(8) link-show command does not provide link-netnsid in all
|
|
|
cbc4cf |
cases (versions ?). Let's try to use "ip netns list-id" as fallback.
|
|
|
cbc4cf |
|
|
|
cbc4cf |
This commit also add possibility to debug the script by $LOG variable.
