## How I did it Depends on sonic-net/sonic-linux-kernel#328 and sonic-net/saibcm-modules#12. #### How to verify it Verified that the image boots up, BGP comes up, and a basic warm-reboot works on VS, broadcom, and mellanox. |

Mellanox non-upstream linux kernel patches
To include non-upstream patches into the sonic-linux image during build time, the INCLUDE_EXTERNAL_PATCHES=y flag has to be provided. By default, the directory pointed by EXTERNAL_KERNEL_PATCH_LOC will be used and it must follow the following structure. To use a publicly accessible tar of the non-upstream patches, also provide the EXTERNAL_KERNEL_PATCH_URL variable

- It should contain a file named series.patch. This should contain a diff that is applied on the sonic-linux-kernel/patch/series file. The diff should include all the non-upstream patches.
- All the patches should be present in the patches folder
- Developers should make sure patches apply cleanly over the existing patches present in the src/sonic-linux-kernel .
Include the non upstream patches while building sonic linux kernel
Set INCLUDE_EXTERNAL_PATCHES=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_PATCHES=y ' target/debs/bullseye/linux-headers-5.10.0-12-2-common_5.10.103-1_all.deb
