However, there are broken TCP implementations (for example, stacks used by Omniswitch 63xx and 64xx models), which send TCP segments without timestamps although they negotiated timestamp support. This patch adds a sysctl variable which tolerates such TCP segments and allows to interoperate with broken stacks.
