net/ipv4 contains around 100 source files containing the IP implementation and various other functionality (UDP, TCP, xfrm, etc.). 30 of them make up the TCP implementation.
I think moving the TCP implementation to a own subdirectory makes the source tree more explorable and well structured. Note: This only affects the TCP Code shared by IPv4 and IPv6, the IPv4 specific part (tcp_ipv4.c and tcp_offload.c) is left in net/ipv4/. This creates the directory, moves the files and updates the Makefiles acordingly.
