How to get LINK BW/SPEED

[Soohong Daniel Park <soohong.park@SAMSUNG.COM>]

Within our spec. there are several parameters/premitives
to get LINK specific information such as Available BW,
SPEED, BER, etc... I am wondering how to get these
information on the local stack. Is it from MAC/PHY of
each standard (I.g., Supported Rate of 802.11) ? or 
do we need any extension or modification along with 
21 premitives ? I need to get accurate and dynamic
LINK information when in motion...It seems a bit
implementation issues though...

Thanks in advance.
