   …nic-net#14652)
   
   #### Why I did it
   
   Facilitate Automatic integration of sdk kernel patches into SONiC. 
   
   **Inputs to the Script:**
   1) `MLNX_SDK_VERSION` Eg: `4.5.4206`
   2) `MLNX_SDK_ISSU_VERSION` Eg: `101` 
    **Note: If nothing is provided the one already present in the sdk.mk file is used**
   3) `MLNX_SDK_SOURCE_BASE_URL:` 
    **Note: If nothing is provided the upstream sdk drivers url is used**
   4) `CREATE_BRANCH: (y|n)` Creates a branch instead of a commit (optional, default: n) 
   5) `BRANCH_SONIC`:  Only relevant when CREATE_BRANCH is y. `Default: master`. 
   
   Note: These should be provided through `SONIC_OVERRIDE_BUILD_VARS ` parameter
   
   **Output:**
   1) Script creates a commit in sonic-linux-kernel with any updates to sdk-kernel patches in sonic in accordance with the version provided by  `MLNX_SDK_VERSION`
   
   **Note: Script Doesn't commit anything to linux-kernel when there aren't any changes required..**  
   
   #### How I did it
   
   1) Added a new make target which can be invoked by calling `make integrate-mlnx-sdk`
   
   ```
   user@server:/sonic-buildimage/src/sonic-linux-kernel$ git rev-parse --abbrev-ref HEAD
   master_6f38dca_integrate_4.5.4206
   
   user@server:/sonic-buildimage/src/sonic-linux-kernel$ git log --oneline -n 1
   d64d1e7 (HEAD -> master_6f38dca_integrate_4.5.4206) Intgerate MLNX SDK 4.5.4206 Kernel Patches
   ```
   
   Changes made will be summarized under `sonic-buildimage/integrate-mlnx-sdk_user.out` file. Debugging and troubleshooting output is written to `sonic-buildimage/integrate-mlnx-sdk.log` files

   #### Limitations:
   1) Assumes that the sdk kernel patches are always upstreamed
   
   #### How to verify it
   
   Build the Kernel and test
