Subject: [PATCH] [Nokia][device-data] Modify the Nokia-7250IXRE platform
 specific reboot script (#14568)

Why I did it

When reboot the chassis by issuing "sudo reboot" on Supervisor card. The internal midplane communication xe0 should be shutdown to avoid double reboot on the linecard.
Added a udev link rule to disable the autoneg on AMD xgbe port Xe0 and Xe1 and make the setting in sync with the peer Broadcom greyhound ports.

How I did it

Modify the Nokia-7250IXRE specific reboot script on the Supervisor card to shutdown the internal interface xe0. Also move reboot linecard code to the top of the script to make sure the notification has been send to Linecard before shutdown the xe0 interface.
Introduced a new rule 80-net-by-driver.link to disable the autoneg on the AMD size. This change requires the latest NDK which contains the change to set the autoneg on the xe0 and xe1 port on the Greyhound.
