|
|
INT Packets |
Added support for forwarding INT packets to the user application for monitoring purposes by matching the BTH acknowledge request bit (bth_a). |
|
IPsec CPS Bulk Allocation |
Improved the IPsec CPS by using bulk allocation. For cases in which log_obj_range == 0, single IPSEC object will be allocated and initialized as before keeping backward compatibility. For better performance, it is recommended to work with IPsec bulk allocation and to initialize IPsec ASO context not via the firmware but via the hardware using ASO WQE. |
