Log message:
this diff introduces the MAXMCLBYTES macro to describe the largest
cluster the generic network stack will be able to give you.
it also recognises that external storage on an mbuf may be bigger than
MCLBYTES. its only when m_pullup or m_pulldown need to allocate
another cluster that they now check the len argument, and now they
do it against MAXMCLBYTES.
this is required for me to do pfsync on jumbo frames as the m_pulldown
for the subregions fail beyond MCLBYTES into the packet.
