NAME
       skb_seq_read - Sequentially read skb data


SYNOPSIS
       unsigned int skb_seq_read  (unsigned int consumed, const u8 ** data,
                                     struct skb_seq_state * st);


ARGUMENTS
       consumed
              number of bytes consumed by the caller so far

       data   destination pointer for data to be returned

       st     state variable


DESCRIPTION
       Reads a block of skb data at &consumed relative  to  the  lower  offset
       specified  to  skb_prepare_seq_read. Assigns the head of the data block
       to &data and returns the length of the block or 0 if the end of the skb
       data or the upper offset has been reached.

       The  caller  is  not required to consume all of the data returned, i.e.
       &consumed is typically set to the number of bytes already consumed  and
       the  next  call  to  skb_seq_read will return the remaining part of the
       block.


NOTE
       Fragment lists within fragments are  not  implemented  at  the  moment,
       state->root_skb could be replaced with a stack for this purpose.
