[chaitanya]

Hi,
  I am a newbie working on tc tool, i want to know whether we have the
following classifiers available 

(1) source MAC address.
(2) destination MAC address.
(3) IEEE 802.1D user priority.
(4) Ethertype (IEEE 802.3, 1998 Length/Type Field).

Can any one help me in finding the help for the above classifiers.
Thanks in advance
