Assign fix netwrk interface name

Hi Friends,

After network hardware or os up-gradation, We normally loose network interface names.

And If you are working in remote location, It become pain to change interfaces settings (ex- ip, rx-tx settings).

Please use below settings to avoid this:-

1) # In /etc/default/grub - ensures eth0/1/2/x like names

GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"

2) # MAC address can be read using following command

root@abc:~# ls /sys/class/net/ | xargs -IX sh -c 'echo X $(cat /sys/class/net/X/address)'

eth0 88:d7:f6:d4:be:37

eth1 88:d7:f6:d4:be:36

eth2 64:3f:5f:01:5a:dc

eth3 64:3f:5f:01:5a:dd

eth4 64:3f:5f:01:5a:c8

eth5 64:3f:5f:01:5a:c9

lo 00:00:00:00:00:00

3) Create /etc/udev/rules.d/70-persistent-net.rules !! FIX MAC ADDRESSES LIST !!
