Subject: [PATCH] xtables-monitor: print packet first
|
|
|
|
The trace mode should first print the packet that was received and
|
|
then the rule/verdict.
|
|
|
|
Furthermore, the monitor did sometimes print an extra newline.
|
|
|
|
After this patch, output is more consistent with nft monitor.
|
|
