The TFTP server provided by dnsmasq supports serving a select boot image
based on the client's MAC or IP address. This allows an administrator
to activate this feature in /etc/config/dhcp. Here is an example
/etc/config/dhcp that configures dnsmasq with --tftp-unique-root=mac:
...
config dnsmasq
option enable_tftp 1
option tftp_root /usr/libexec/tftpboot
option tftp_unique_root mac
config boot router
option serveraddress 192.168.1.1
option servername tftp.example.com
option filename openwrt-initramfs-kernel.bin
...
With this configuration, dnsmasq will serve
/usr/libexec/tftpboot/00-11-22-33-44-55/openwrt-initramfs-kernel.bin to
the client with MAC address 00:11:22:33:44:55.
