- Why I did it

Update SDK 4.4.1956 and FW *.2008.1956

Bugs fixes:

  1. Link | Clear operational speed when link is not active
  2. Spectrum-2, SN3800 | On rare occasion, link flapping due to bad BER causes traffic loss
  3. Spectrum-3 | On rare occasion, link flapping due to bad BER causes traffic loss as a result of new PAM4 link maintenance flow on Spectrum-3 devices
  4. Shared Buffers | On rare occasion, modifying shared buffers on a system with split port while traffic is running may cause the firmware to get stuck
  5. Spectrum-3, SN4700 | Fence may fail while running 400GbE 8x port when modifying mirror session configurations under traffic

- How I did it

  1. Change SDK and FW version in sdk.mk and fw.mk
  2. Update Switch-SDK-drivers pointer to 4.4.1956

- How to verify it
