        to packet, possible failures:

	1. EOF occured when reading from file, it's really an error

           as data_len is >=0 there's supposed to be more bytes available.

           file->error will have been set to number of bytes left to read

        2. Read was interrupted, file->error would normally be set to -1

        3. Failed to allocate memory for packet, my_errno

           will be ENOMEM(file->error shuold be 0, but since the

           memory allocation occurs before the call to read it might

           be uninitialized)
