RFR[8240901]: 'Add a test to check that large datagrams are sent/received on the network correctly'

[Patrick Concannon]

Hi,

Could someone please review my fix for JDK-8240901 — ‘Add a test to check that large datagrams are sent/received on the network correctly’ ?

The tests `java/net/DatagramSocket/SendReceiveMaxSize.java` and `java/net/DatagramSocket/SendReceiveMaxSize.java` have been updated to check (on all platforms) that the sending and receiving of large datagrams across a network are sent, fragmented, and re-assembled correctly. Previously, this check was performed on macOS only.

issue: https://bugs.openjdk.java.net/browse/JDK-8240901

Kind regards,
Patrick
