Subject: [PATCH RHEL7 4/7] bnxt_en: Suppress error messages when querying
|
|
|
8fbaf1 |
DSCP DCB capabilities.
|
|
|
8fbaf1 |
|
|
|
8fbaf1 |
Some firmware versions do not support this so use the silent variant
|
|
|
8fbaf1 |
to send the message to firmware to suppress the harmless error. This
|
|
|
8fbaf1 |
error message is unnecessarily alarming the user.

Fixes: afdc8a84844a ("bnxt_en: Add DCBNL DSCP application protocol support.")
