NV Configurations via the Relevant Reset Flow

Added pci_rescan_needed field to the MFRL access register to indicate whether a PCI rescan is needed based on the NV configurations issued by the software.

Note: If the Keep Link Up NV configuration is changed, phyless reset will be blocked.

MADs

Added a new MAD of class SMP that has the attributes hierarchy_Info as defined in the IB Specification and is used to query the hierarchy information stored on the node and the physical port.

ICM Pages

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

XRQ QP Errors Enhancements

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.

ibstat

Updated the ibstat status reported when the phy link is down. Now QUERY_VPORT_STATE.max_tx_speed of UPLINK will not be reported as 0 anymore.

SMPs

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.

SW Steering Cache

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.
