Subject: [PATCH] ethdev: introduce generic dummy packet burst function
|

|
|

|
Multiple PMDs have dummy/noop Rx/Tx packet burst functions.
|
||
|
|
|
||
|
|
These dummy functions are very simple, introduce a common function in
|
||
|
|
the ethdev and update drivers to use it instead of each driver having
|
||
|
|
its own functions.
