ePMP 1000 SM cannot be associated with OUT OF CELL reason after upgrade to 4.5.0

Hello, i have issue after upgrade to 4.5.0.

Hardware: PTP link of two ePMP 1000 NonGPS Synced Radio (Force 110)

Firmware before upgrade: 4.4.3

Firmware after upgrade: 4.5.0

AP mode: ePTP Master

SM mode: ePTP Slave

Frequency: 5160

Channel Bandwidth: 20

First i upgraded SM, after reboot link to AP is OK, then upgrade AP and after reboot have error in log:

Rebooting AP and SM does not help. Just downgrade AP to 4.4.3 and link was restored.

Make sure that you have the 1000 sm set to eptp slave and are using the same frame size as the AP. 

We have found it helpful to set the distance for allowed links to be a few more miles that needed. For some reason being too close to the actual link distance caused link start issues.

We have stuck to 4.4.3 for our ptp links because 4.5 breaks management vlan access that is imperative to our use.

Sure, SM set to eptp slave. Frame size and max range are not allowed for set in eptp mode. (My link distance is about 17.5km)

On ver 4.4.3 i am use management vlan, after update to 4.5 management vlan settings are the same and fully work for me.

Today i additionally did some tests with 4.5 firmware, so i can concluse that eptp mode not working on 4.5. Carefully check all options on both side, power reboot both side, nothing help. After change AP and SM to TDD mode it`s working fine.
