tcp: add TCP_OLD_SEQUENCE drop reason
tcp_sequence() uses two conditions to decide to drop a packet, and we currently report generic TCP_INVALID_SEQUENCE drop reason. Duplicates are common, we need to distinguish them from the other case. I chose to not reuse TCP_OLD_DATA, and instead added TCP_OLD_SEQUENCE drop reason.

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.
