Subject: [PATCH 1/2] bonding: change AD_LINK_SPEED_BITMASK to enum to suport more speed
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 the old
speed field, 5 bits are for speed [1|10|100|1000|10000]Mbps as
below:
--------------------------------------------------------------
Port key :| User key | Speed | Duplex|
--------------------------------------------------------------
16 6 1 0
This patch keeps the old layout, but changes AD_LINK_SPEED_BITMASK
from bit type to an enum type. In this way, the speed field can
expand speed type from 5 to 32.
