Great. Thank you!

If I understand correctly it means I can use kqueue on Linux, right?
In this case, may I ask how to compile Freeradius (< 4.x) with kqueue
support on Linux?

First I've tried to compile it on Amazonlinux:2 including compiling
libkqueue. This didn't work.

https://wiki.freeradius.org/building/libkqueue-rpm

Then I tried to compile it on Ubuntu 22.04 because libkqueue for
ubuntu exists as a package.
In both cases ./configure script reports that kqueuue is not supported.


```
checking for inet_ntop... yes
checking for inet_pton... yes
checking for initgroups... yes
checking for kqueue... no
checking for localtime_r... yes
checking for mallopt... yes
checking for mkdirat... yes
checking for openat... yes
checking for pthread_sigmask... yes
checking for setlinebuf... yes
```
