Subject: [PATCH 170/189] net/hns3: fix DCB reconfiguration
|
|
|
|
Whether the enable bit of the pfc ("pfc_en") is changed or not is one of
|
|
the conditions for reconfiguring the DCB. Currently, pfc_en is not
|
|
rolled back when DCB configuration fails. This patch fixes it.
|
|
|
|
Fixes: 62e3ccc2b94c ("net/hns3: support flow control")
