retrive data from mbuf chain

Hi, I am new to FreeBSD kernel programming. Currently I am trying to work on mbuf data manupulation. >From my understanding: data (payload) is stored into one or more mufs which are chained together through m_next pointer. Now, I need to retrive all data in mbuf chain ( mbufs linked by m_next).

uma_zcreate and number of items to create
