When received packet is copied to guests's rx queue, data buffers of rx queue could be smaller that data buffer of input packet, so data of input packet is copied to each rx buffer, thus each rx buffer will be a packet with dynamically created header. Fields of such header are initialized from header of input packet(except length field which value is depends on number of bytes copied to rx buffer). But in SEQPACKET case, we also need to take care of record delimeter bit: if input packet has this bit set, we don't copy it to header of packet in rx buffer, except case when such rx buffer is last part of input packet. Otherwise, we will get sequence of packets with delimeter bit set, thus braking record bounds. Also remove ignore of non-stream type of packets, handle SEQPACKET feature bit.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
