@deepak-singhal0408 This PR a platform specified data (linecard_reboot_timeout=180) which is associated with https://github.com/sonic-net/sonic-platform-daemons/pull/480 and allow each vendor has own value. If this define is not found, the linecard_reboot_timeout will default to 180 seconds. Do we need merge this PR? I think it is good to merge it, so that other vendor can use it as example when they need to use a different value.
