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
