Subject: [PATCH 16/26] net/hns3: support multiple TC MAC pause
|
|
|
|
MAC PAUSE can take effect on a single TC or multiple TCs, depending on the
|
|
hardware. For example, the Kunpeng 920 supports MAC pause in a single TC,
|
|
and the Kunpeng 930 supports MAC pause in multiple TCs. This patch
|
|
supports MAC PAUSE in multiple TC for some hardware.
