&nbsp;because imx6 is embeded system,so makefile changed,two function not define,add \
two function.

makefile:
KERN_DIR = /root/imx6/linux-3.14.52
obj-m += e1000e.o

e1000e-objs := netdev.o ethtool.o ich8lan.o mac.o nvm.o phy.o&nbsp;&nbsp;&nbsp; \
manage.o 80003es2lan.o 82571.o param.o kcompat.o all:
&nbsp;&nbsp; &nbsp;make -C $(KERN_DIR) M=`pwd` modules 
&nbsp;
clean:
&nbsp;&nbsp; &nbsp;make -C $(KERN_DIR) M=`pwd` modules clean
&nbsp;&nbsp; &nbsp;rm -rf modules.order
