Merge branch 'bonding_4ad' 

Xie Jianhua says:

====================
bonding: Introduce 4 AD link speed

The speed field of AD Port Key was based on bitmask, it supported 5
kinds of link speed at most, as there were only 5 bits in the speed
field of the AD Port Key.  This patches series change the speed type
(AD_LINK_SPEED_BITMASK) from bitmask to enum type in order to enhance
speed type from 5 to 32, and then introduce 4 AD link speed to fix
agg_bandwidth.
====================
