Subject: [PATCH 424/431] net/hns3: enable PFC for all user priorities
|
|
|
|
[ upstream commit aae6989df36c105b917cf69975c075dfde2e6b84 ]
|
|
|
|
When user set TC number to 4 and enable PFC and ETS by dev_configure,
|
|
driver only enable user priority 0-3.
|
|
The packet with user priority 4-7 cannot trigger PFC frame.
|
|
|
|
Fix by enabling PFC for all user priorities.
|
|
|
|
By the way, the nb_tcs from user can never be 0 because of the ahead
|
|
check in driver. So remove this redundant code.
|
|
|
|
