From 1e066431a45a67321abcd134e888205fc633bd41 Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Wed, 4 May 2016 13:30:37 +0100 Subject: [tcpip] Do not fall back to using unoptimised TCP/IP checksumming Require architecture-specific code to make a deliberate choice to use the unoptimised generic_tcpip_continue_chksum() function, if there is no optimised version available.
