Feature/Change	Description
32.41.1000
SuperNIC Mode	SuperNIC mode is now the default mode for the following SKUs: 900-9D3B4-00CC-EA0 900-9D3B4-00SC-EA0 900-9D3B4-00CV-EA0 900-9D3B4-00SV-EA0 900-9D3B4-00EN-EA0 900-9D3B4-00PN-EA0 900-9D3D4-00EN-HA0 900-9D3D4-00NN-HA0
virtio-net Emulation Device	Added support for VIRTIO_NET_F_HASH_REPORT(57) bit for the virtio-net emulation device.
virtio-net Emulation Device	Added support for VIRTIO_NET_F_SPEED_DUPLEX(63) bit for the virtio-net emulation device.
virtio Full Emulation	Added support for virtio full emulation scale up to 2k devices.
ODP Event	Added support for the following prefetch fields on ODP event: pre_demand_fault_pages, post_demand_fault_pages.
TRNG FIPS Compliance	Implemented Deterministic Random Bit Generator (DRBG) algorithm on top of firmware TRNG (the source for raw data input) in accordance with NIST SP800-90A.
PSP	Added support for PSP in Hardware Steering.
NVConfig	Added a new NVConfig option to copy AR bit from the BTH header to the DHCP header.
Generic Emulation	Generic Emulation enables the programmers to define their own custom PCI devices to be exposed to the host using the new hot-plug/unplug function flow. The API enables the programmer to control the device BARs layout, software defined BAR registers and hardware offloading mechanisms (MSI-X, DBs).
Steering	Added the option provide field's offset and length in Steering add_action option.
Steering Match	Added support for steering match on packet l4_type through FTG/FTE.
RSHIM PF	RSHIM PF functionalities are now dynamically locked/unlocked during runtime by Platform BMC via the NC-SI commands.
BAR Pages	Added support for 64KB pages. Note: Configuring BAR_PAGE_ALIGNMENT to ALIGN_64KB(2) while one of the following is configured will cause the device to ignore the BAR_PAGE_ALIGNMENT configuration: PF_NUM_PF_MSIX>256 on any of the Physical Functions VIRTIO_EMULATION_HOTPLUG_TRANS/VIRTIO_NET_EMULATION_PF_PCI_LAYOUT/ VIRTIO_NET_EMULATION_VF_PCI_LAYOUT/ VIRTIO_BLK_EMULATION_PF_PCI_LAYOUT/ VIRTIO_BLK_EMULATION_PF_PCI_LAYOUT=VIRTIO_TRANSITIONAL(1)
ATF/UEFI Version Query	Added the ability to query ATF/UEFI version via the MISOC register.
Programmable Congestion Control	Added support for PCC NP for RTT according to the IFA2.0 standards.
Flex Parser Merge Mechanism	Extended Flex Parser merge mechanism to support hardware capabilities.
Flex Parser	Enabled the option to disable the native parser when the parse graph node is configured with the same conditions.
Flex Parser	Added support for father/son headers parsing.
LRO	Added support for tunnel_offload in LRO.
