More information about RPC-with-TLS and some brief set-up guidance
are to be provided in a separate man page in Section 7.
Signed-off-by: Chuck Lever <chuck.lever@xxxxxxxxxx>
Question: commit b5e4539f already add this RPC-with-TLS
update to the man page. So do you want me to revert b5e4539f
and replace it with this patch?
Hrm, I didn't remember sending you a client-side man page update.
I thought I was waiting for the in-kernel parts of the client
TLS work to land, which they've done now in v6.5-rc.
If it's no trouble, go ahead and replace that one.
Not a problem... I'll make it work....
