Mellanox non-upstream linux kernel patches

To include non-upstream patches into the sonic-linux image during build time, this folder must contain a patch archive.

Structure of the patch archive

It should contain a file named series. series should provide an order in which the patches have to be applied

admin@build-server:/sonic-buildimage/src/sonic-linux-kernel$ cat linux-5.10.103/non_upstream_patches/series
mlx5-Refactor-module-EEPROM-query.patch
mlx5-Implement-get_module_eeprom_by_page.patch
mlx5-Add-support-for-DSFP-module-EEPROM-dumps.patch

All the patches should be present in the same folder where series resides.
Developers should make sure patches apply cleanly over the existing patches present in the src/sonic-linux-kernel .
Name of the tarball should match with the one specified under EXTERNAL_KERNEL_PATCH_TAR

Example

admin@build-server:/sonic-buildimage/platform/mellanox/non-upstream-patches$ tar -tf patches.tar.gz
./
./mlx5-Implement-get_module_eeprom_by_page.patch
./mlx5-Add-support-for-DSFP-module-EEPROM-dumps.patch
./series
./mlx5-Refactor-module-EEPROM-query.patch

Include the archive while building sonic linux kernel

Set INCLUDE_EXTERNAL_PATCH_TAR=y using SONIC_OVERRIDE_BUILD_VARS to include these changes before building the kernel.

Eg: NOJESSIE=1 NOSTRETCH=1 NOBUSTER=1 make SONIC_OVERRIDE_BUILD_VARS=' INCLUDE_EXTERNAL_PATCH_TAR=y ' target/debs/bullseye/linux-headers-5.10.0-12-2-common_5.10.103-1_all.deb
