From: Matan Barak <redacted> Some flow steering namespace initialization (i.e. egress namespace) might depend on FPGA capabilities. Changing the initialization order such that the FPGA will be initialized before flow steering. Flow steering fs cmds initialization might depend on IPSec capabilities. Changing the initialization order such that the IPSec will be initialized before flow steering as well.
