Log message:
In ddb(4) print mbuf chain and packet list.
For debugging hardware offloading, DMA requirements, bounce buffers,
and performance optimizations, knowing the memory layout of mbuf
content helps.
Implement /c and /p modifiers in ddb show mbuf. It traverses the
pointer m_next for mbuf chain or m_nextpkt for packet list. Show
mbuf type, data offset, mbuf length, packet length, cluster size,
and total number of elements, length and size.
