Message-Id: <20171003222213.7996-2-richard_siegfried@systemli.org>
Date: Wed, 4 Oct 2017 00:22:11 +0200
From: Richard Sailer <richard_siegfried@...temli.org>

Subject: [PATCH net-next 1/3] net/ipv4: Move shared tcp code to own subdirectory
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.
Signed-off-by: Richard Sailer <richard_siegfried@...temli.org>
