[Drbd-dev] "data-integrity-alg" can't be worked in 9.0.x

[박경민]

Hello.
I'm a software engineer in Mantech.

I'm testing about '*data-integrity-alg crc32c'.*
and resync failed in drbd 9.0.0 and 9.0.1.
It was ocurred to connect/disconnect continuously because of ProtocolError.

But, It works in 8.4.6 and 8.4.7 successfully.

Please, look into config & log
