Announcing v4.5.1

This release contains contributions from a record number of new contributors. This is greatly appreciated since I am a team of one, and do Tcpreplay maintenance in my spare time.

There are many bug fixes and new features. Most notable features:

• AF_XDP socket support - if you have a newer Linux kernel, you will be able to transmit at line rates without having to install 3rd party kernel modules (e.g. netmap, PF_RING)
• -w tcpreplay option - this overrides the -i option, and allows you to write to a PCAP file rather than an interface
• --include and --exclude tcpreplay options - allows replay of a list of specific packet numbers to replay. This may slow things down, so consider using in combination with -w.
• --fixhdrlen tcpreplay option - added to control action on packet length changes
• -W tcpreplay option - suppress warnings when replaying
• SLL2( Linux "cooked" capture encapsulation v2)
• Haiku support
