Astra-sim 1.0_ns3编译问题

目前github上的Astra-sim 1.0_ns3的子模块地址出错了，
修改.gitmodules，应为：

[submodule "extern/googletest"]
	path = extern/googletest
	url = https://github.com/google/googletest.git
[submodule "extern/network_backend/analytical"]
	path = extern/network_backend/analytical
	url = https://github.com/astra-sim/analytical.git
[submodule "extern/network_backend/garnet/gem5_astra"]
	path = extern/network_backend/garnet/gem5_astra
	url = https://github.com/georgia-tech-synergy-lab/gem5_astra.git
[submodule "extern/compute/SCALE-Sim"]
	path = extern/compute/SCALE-Sim
	url = https://github.com/scalesim-project/scale-sim-v2.git
[submodule "extern/network_backend/ns3-interface"]
	path = extern/network_backend/ns3
	#url = https://github.com/astra-sim/astra-network-ns3.git
    url = https://github.com/astra-sim/deprecated-astra-network-ns3

然后再git submodule update --init
