Galera with rsync on FreeBSD broken

The FreeBSD specific patch for rsync Galera SST doesn't work.

https://github.com/MariaDB/server/commit/cf1b0c1ace3584fcd807e0643d30956baa5de2c2#diff-ce1fe90d058fac6e05405aced56e6f83

local port_info=$(netstat -46lp $\{rsync_port\} 2>/dev/null | \

grep ":$\{rsync_port\}")

netstat -p on FreeBSD is for protocol, not port number or program/PID. This command always results in the following error message being sent to /dev/null

netstat: 4444: unknown or uninstrumented protocol

From man:

     -f	address_family,	-p protocol

	   Limit display to those records of the specified address_family or a

	   single protocol.  The following address families and	protocols are

	   recognized:

	   Family		       Protocols

	   inet	(AF_INET)	       divert, icmp, igmp, ip, ipsec, pim,

				       sctp, tcp, udp

	   inet6 (AF_INET6)	       icmp6, ip6, ipsec6, rip6, tcp, udp

	   pfkey (PF_KEY)	       pfkey

	   netgraph, ng	(AF_NETGRAPH)  ctrl, data

	   unix	(AF_UNIX)

	   link	(AF_LINK)

	   The program will complain if	protocol is unknown or if there	is no

	   statistics routine for it.

Additionally, specifying both -4 and -6 at the same time doesn't work. The latter will overwrite the former. If it is specified as netstat -46, only IPv6 is used. If it is specified as netstat -64, only IPv4 is used.

One other note: there is no mention in the FreeBSD man page of netstat being able to return PID at all, which is the whole point of this call to begin with. Searching around online, everyone is suggesting using lsof to get this information, which is exactly what was happening BEFORE this broken OS specific patch was applied.
