RoCE: Adaptive Timer	Enabled ADP timer to allow the user to configure RC or DC qp_timeout values lower than 16.
QoS Priority Trust Default State	QoS priority trust default state can now be changed using the new nvconfig below: QOS_TRUST_STATE_P1 QOS_TRUST_STATE_P2 The values that can be used to set the default state are: TRUST_PORT TRUST_PCP TRUST_DSCP TRUST_DSCP_PCP

16.33.1048
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.
