Subject: [PATCH RFC net-next 1/5] bonding: Expand speed type for AD Port Key
From: Jianhua Xie <Jianhua.Xie@...escale.com>
Port Key was determined as 16 bits according to the link speed,
duplex and user key (which is yet not supported), in which key
speed was 5 bits for 1Mbps/10Mbps/100Mbps/1Gbps/10Gbps as below:
--------------------------------------------------------------
Port key :| User key | Speed | Duplex|
--------------------------------------------------------------
16 6 1 0
This patch is expanding speed type from 5 bits to 9 bits for other
speed 2.5Gbps/20Gbps/40Gbps/56Gbps and shrinking user key from 10
bits to 6 bits. New Port Key looks like below:
--------------------------------------------------------------
Port key :| User key | Speed | Duplex|
--------------------------------------------------------------
16 10 1 0
