[yocto] Compiling openvswitch module in yocto

[Gaurang Shastri]

Hi,

In your recipe, you just need to enable,

EXTRA_OECONF = "--with-linux=${STAGING_KERNEL_DIR} KARCH=${TARGET_ARCH}"

This will build openvswitch module against your kernel source. I did this
and I did not find any issues and it built module against my kernel.

Can you paste more logs here ??
