3.16.78-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Xin Long <lucien.xin@xxxxxxxxx>
commit a1794de8b92ea6bc2037f445b296814ac826693e upstream.
As the annotation says in sctp_do_8_2_transport_strike():
"If the transport error count is greater than the pf_retrans
threshold, and less than pathmaxrtx ..."
It should be transport->error_count checked with pathmaxrxt,
instead of asoc->pf_retrans.
Fixes: 5aa93bcf66f4 ("sctp: Implement quick failover draft from tsvwg")
