From 26859240e4ee701e0379f08634957adaff67e43a Mon Sep 17 00:00:00 2001 From: Akhmat Karakotov Date: Mon, 31 Jan 2022 16:31:22 +0300 Subject: txhash: Add socket option to control TX hash rethink behavior Add the SO_TXREHASH socket option to control hash rethink behavior per socket. When default mode is set, sockets disable rehash at initialization and use sysctl option when entering listen state. setsockopt() overrides default behavior.
