I was able to figure out how to pass the variables to the FreeBSD
mfsroot. I did so by modifying the grub.cfg file like the below:
menuentry "freebsd82-x86_64" {
kfreebsd /boot/kernel/kernel
kfreebsd_loadenv /boot/device.hints
kfreebsd_module /boot/mfsroot.gz type=3Dmfs_root
set kFreeBSD.vfs.root.mountfrom=3Dufs:/dev/md0c
set kFreeBSD.boot.nfsroot.server=3D$pxe_default_server
set kFreeBSD.boot.netif.hwaddr=3D$net_pxe_mac
set kFreeBSD.boot.netif.ip=3D$net_pxe_ip
set kFreeBSD.dhcp.host-name=3D$net_pxe_hostname
}
