Especially since this is what will happen anyway since your kernel patch
to expire unauthenticated stations has been applied.
Manually resending an authentication frame might be another option, but
it will not work if the peer does not support auth exchange at all.
On the other hand, starting an EAPOL exchange in a lossy environement is
a bad idea, even if both peers runs wpasupplicant on linux. This cab
easily end up in conditions where one peer will detect an hacking
attempt and the exchange will stall, or even in funnier things when
EAPOL 4/4 is dropped, since the supplicant has security enforced and the
authenticator has not.
