What thagrol said. Assuming your buildroot image is self contained and does not support mounting its root over NFS, I would suggest not using netbooting via TFTP but instead to use HTTP boot. Not only does this remove the requirement that the boot image is provided within the same broadcast domain, it also allows you to send a complete (up to 96MB, IIRC) image to the Pi which is then fully used from RAM.
