Subject: [PATCH] net/hns3: restrict tunnel flow rule to one header
|
||
|
|
|
||
|
|
[ upstream commit 8887c207b9373a1875031c5346706f698322d66d ]
|
||
|
|
|
||
|
|
The device's flow director supports a maximum of one tunnel header, if
|
||
|
|
passed more than one tunnel header from rte-flow API, the driver should
|
||
|
|
return error.
|
||
|
|
|
