[David Waitzman]

I should have explicitly stated MACsec, i..e. "For how many nodes maximum has wpa_supplicant been tested to work using MACsec 802.1AE?" (it was implied by "MKPDU").

You could split the peer lists across multiple MKPDUs per the standards, which would fix that limit.  (but then other constraints might come into play.)
