Compile custom iproute2 in LEDE


I am trying to add a patch to iproute2 to supports options related to MP-TCP in LEDE. In the following path:


I find iproute2 folder and I add a patch to support MP-TCP options. However, it seems that LEDE prefers iproute2 of busybox and it does not compile this package. So my question is how can I enforce LEDE to compile and install iproute2 in the previous path instead of busybox?
