- Why I did it
Updated SDK 4.4.0940 and FW xx.2007.1244

Bugs fixes:

• Link Added GA-level support for link auto-negotiation on Spectrum-2 and Spectrum-3 systems for 100GbE (25GbEx4)
• While using custom FPGA with Spectrum-based systems, 50GbE RSFEC does not raise a link while using auto-negotiation or force mode
• SDK does not create egress mirror ACL rule to match L4 source port
• VXLAN traffic dropped during warmboot
• On rare occasions on Spectrum-2 systems, while deleting ACLs or modifying routes, the firmware will hang and will not accept additional configuration
• On Spectrum-2 and Spectrum-3 systems, when configuring more than 16 LAGs, the Multicast container/Flooding vectors may overwrite each other's configuration
• In SN4700 system, link flapping observed when fully populated system (i.e. using 32 ports at 400GbE or using 64 ports at 200GbE) is connected
• In some cases, with mix split port configuration on Spectrum-3 systems, bridge traffic would egress a trunk port without a VLAN

- How I did it
Updated appropriate sub-modules and versions

- How to verify it
Build an image and verify all is up and running
