RFC 6458 (SCTP Sockets API) Section 8.2.2. Peer Address Information (SCTP_GET_PEER_ADDR_INFO) defines that spinfo_srtt is in miliseconds, yet we were using it in jiffies.
Fix it by converting before assigning, similarly to RTO. Signed-off-by: Marcelo Ricardo Leitner <[email protected]> --- I hope this is not considered UAPI breakage.
