[Mellanox] Non upstream patches for hw-mgmt V.4.0020.4104

[stephenxs]

Why I did it

Add non-upstream kernel patches for the Nvidia platforms
These patches are not yet upstream but needed for new technology.
A flow to upstream them is in progress and once they will be approved they will be moved officially to sonic-linux-kernel.
Till then to include them in the build (not must) the build option INCLUDE_EXTERNAL_PATCH_TAR=y should be included

How I did it

Zip all the patches in to a tar.gz tarball.

How to verify it

Manually test

I'd suggest either overriding this flag https://github.com/sonic-net/sonic-buildimage/blob/master/platform/mellanox/rules.mk#L55, or zip the patches.tar to patches.tar.gz and thus we don't have to provide EXTERNAL_KERNEL_PATCH_TAR while building, Also did you test compiling the kernel, did the patches apply without any conflicts?

Hi
Thanks for reviewing it.
I did test to compile it and manually checked that all the patches had been successfully applied.
Regarding the tarball, what's the difference between .tar and .tar.gz?

Hi @stephenxs I believe if you have .tar.gz you need not have to override EXTERNAL_KERNEL_PATCH_TAR during build and just setting the flag INCLUDE_EXTERNAL_PATCH_TAR=y should be sufficient since the default value as Vivek pointed out is below
override EXTERNAL_KERNEL_PATCH_TAR := $(BUILD_WORKDIR)/$(PLATFORM_PATH)/non-upstream-patches/patches.tar.gz

I recommend updating it to gz for simplicity during building

Please update tar to tar.gz

I see. I think

EXTERNAL_KERNEL_PATCH_TAR

Got your point. I thought tar -xf doesn't work for .gar.gz file. Now I understand it does work.
Thank you for clarifying.

[stephenxs]

Please update tar to tar.gz

Updated.
