From f8a1a636c2a940d37dba9153bcfe687a802745fb Mon Sep 17 00:00:00 2001 From: Sheng Li Date: Tue, 22 Mar 2016 16:06:23 +0800 Subject: net: hns: fixed portid bug in sending manage pkt In chip V2, the default value of port id in tx BD is Zero. If it is not configurated to the other value, all management packets will be sent out from port0. So port_id in the tx BD needs to be updated when sending a management packet. In V2 chip, when sending mamagement packets, the driver should config the port id to BD descs. Signed-off-by: Sheng Li Signed-off-by: Yisen Zhuang Signed-off-by: David S.
