This is already set in the generic configuration for most targets:
-----------------
:~/openwrt/openwrt/target/linux$ git grep TCP_CONG_ADVANCED
generic/config-5.4:CONFIG_TCP_CONG_ADVANCED=y
layerscape/armv7/config-5.4:# CONFIG_TCP_CONG_ADVANCED is not set
layerscape/armv8_64b/config-5.4:# CONFIG_TCP_CONG_ADVANCED is not set
zynq/config-5.4:# CONFIG_TCP_CONG_ADVANCED is not set
---------------
I would prefer if we set if for all targets, then it is not needed here
any more.

Is AutoProbe working here?
