Subject: [PATCH] [networking] Collect 'ethtool -e <device>' conditionally only
|
|
|
8bcace |
|
|
|
8bcace |
EEPROM dump collection might hang on specific types of devices, or
|
|
|
8bcace |
negatively impact the system otherwise. As a safe option, sos report
|
|
|
8bcace |
should collect the command when explicitly asked via a plugopt only.
|
|
|

|

Resolves: #2376
