I appreciate the pointer to information on how to make this message go
away on my system, but I intended the bug report as a request to make
wpa_supplicant less chatty by default.

My question above still applies: Does wpa_supplicant really need to log
every time rekeying occurs?  What value does this provide?  Could this
message become something that only appears at -v or above, rather than
by default?

Thanks,
