OpenVPN always allowed 8 ACKs in P_ACK_V1 packets but only used
up to 4 in other control packets. Since Softether drops all packets with
more than 4 ACKs it also drops legimate P_ACK_V1.

Could you change the commit's title to something like Proto_OpenVPN: Set max allowed ACKs to 8 for P_ACK_V1, please?
