Hi,
What I wanted to ask is: why does FreeBSD kqueue implementation treat
`SO_RCVLOWAT` as a raw packet size watermark, and not using the actual
data size for filtering out events?
It looks like SO_RCVLOWAT refers to the number of bytes in the socket
buffer, not raw packet bytes. In the case
Hello again!
I just realized that the wording was probably a bit off.

I am totally fine with the fact that it triggers

Which basically sends a 0-length UDP packet to a server and polls
kqueue events on the server fd.
Return 1 kevent on FreeBSD, and blocks indefinitely without
returning any events on OSX.

terms of
packet data bytes, not just raw packet size. And this is how `NOTE_LOWAT`
actually
works there, right?
Could anyone
