From: Miri Korenblit <miriam.rachel.korenblit@xxxxxxxxx> The max active links that are supported by the FW is hard coded. This is wrong since this value is HW-dependent. Fix this by determining according to the actual HW. Also remove a redundant check that the number of active links doesn't exceeds the maximum.
