please check the following in your NFSROOT:

1. /usr/share/initramfs-tools/scripts/live

   in function Arguments there should be something like 

     BOOTIF=*)
                                BOOTIF="${x#BOOTIF=}"
                                ;;


and in  function do_netmount

there should be something similar like this:

     if [ -n "${BOOTIF}" ]; then
                # pxelinux sets BOOTIF to a value based on the mac
address of the
                # network card used to PXE boot, so use this value for
DEVICE rather
                # than a hard-coded device name from initramfs.conf.
this facilitates
                # network booting when machines may have multiple
network cards.
                # pxelinux sets BOOTIF to 01-$mac_address

                # strip off the leading "01-", which isn't part of the
mac
                # address
                temp_mac=${BOOTIF#*-}

                # convert to typical mac address format by replacing "-"
with ":"
                bootif_mac=""
                IFS='-'
                for x in $temp_mac ; do
                        if [ -z "$bootif_mac" ]; then
                                bootif_mac="$x"
                        else
                                bootif_mac="$bootif_mac:$x"
                        fi
                done
                unset IFS

                # look for devices with matching mac address, and set
DEVICE to
                # appropriate value if match is found.
                for device in /sys/class/net/* ; do
                        if [ -f "$device/address" ]; then
                                current_mac=$(cat "$device/address")
                                if [ "$bootif_mac" = "$current_mac" ];
then
                                        DEVICE=${device##*/}
                                        break
                                fi
                        fi
                done
        fi
