unsigned int skb_seq_read (unsigned int consumed, const u8 ** data, struct skb_seq_state * st);
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.
Fragment lists within fragments are not implemented at the moment, state->root_skb could be replaced with a stack for this purpose.
