From caf8ed933bd6dee39301bf77428e604d51aa9095 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Fri, 8 Mar 2024 23:10:15 +0100 Subject: [PATCH] selftests: mptcp: use += operator to append strings [ Upstream commit e7c42bf4d320affe37337aa83ae0347832b3f568 ] This patch uses addition assignment operator (+=) to append strings instead of duplicating the variable name in mptcp_connect.sh and mptcp_join.sh. This can make the statements shorter. Note: in mptcp_connect.sh, add a local variable extra in do_transfer to save the various extra warning logs, using += to append it. And add a new variable tc_info to save various tc info, also using += to append it. This can make the code more readable and prepare for the next commit.
