Description

https://github.com/microsoft/msquic/blob/5b921c9e187d2c59a43ec285be1a06e99349d1b2/src/platform/datapath_epoll.c#L1173-L1195

My understanding is that this code always set SO_REUSEPORT for a server, and you will not get the address already in use when two servers use the same address, what is the motivation for this? did you consider making it configurable?

Contributor guide

Research direction
Investigate the current SO REUSEPORT usage in datapath epoll.c and propose a configuration option to enable/disable port sharing, ensuring address conflicts are reported when disabled.
