Request for review: kern/47920

[Gleb Smirnoff]

  Dear sirs,

could you take a look at 
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/47920

 This problem is really annoying: large PPPoE network
can be DoSed with one non-standard packet. Moreover,
if there is >1 FreeBSD machine in network, it is really
difficult to return network to normal behavior.

The patch, I have sent (the last one), has been tested
since PR open date till now on 2 big PPPoE concentrators
serving 50 - 200 PPPoE clients each.
