and when the latency reduces and it is safe to be more responsive again:
[knet]: [debug] pmtud: Starting PMTUD for host: 1 link: 0
[knet]: [debug] pmtud: Decreasing PMTUd response timeout multiplier to (64) for host 1 link: 0
[knet]: [debug] pmtud: PMTUD completed for host: 1 link: 0 current link mtu: 65429
....
testing this patch on normal hosts is a bit challenging tho.
Patch was tested by hardcoding a super low timeout here:
diff --git a/libknet/threads_pmtud.c b/libknet/threads_pmtud.c
index 4f0ba0f..5e2b89b 100644

and using a long running version of api_knet_send_crypto_test with a short PMTUd setfreq (10 sec).
