Log message:
allow wccp processing to be enabled per interface with the link0 flag.
this also changes the wccp handling to peek into it's payload to
determine whether it is wccp 1 or 2. wccp1 says the gre header is
followed by ipv4, while wccp2 says there's a small header before
the ipv4 packet. the wccp2 header cannot have 4 in the first nibble,
while ipv4 must have 4 in the first nibble. the code now looks at
the nibble to determine whether it should strip the wccp2 header
or not.
