ICM Pages

Added a new register (vhca_icm_ctrl access_reg) to enable querying and limiting the ICM pages in use.

Enhanced the XRQ QP error information provided to the user in case QP goes into an error state. In such case, QUERY_QP will provide information on the syndrome type and which side caused

the error.

NetworkPort Schema Replacement

Replaced the deprecated NetworkPort schema with Port schema in NIC RDE implementation.

Disabled the option to send SMPs from unauthorized hosts.

Firmware Steering

Enabled the option to modify the ip_ecn field in the packet header in firmware steering.

Modified the TX or RX cache invalidation behavior. TX or RX cache invalidation now does not occur automatically but only when the software performs the sync operation using the using sync_steering command.

Mega Allocations in Bulk Allocator Mechanism

Modified the maximum bulk size per single allocation from "log_table_size - log_num_unisizes", to allocate any range size, to remove limitations that HWS objects such as counters and modify arguments might encounter.
