Sorry, didn't realise you were waiting for feedback; thought you were still
working on the IPv6 stuff.


Installed bbcp-20150116 onto FreeBSD 9.3p5.  Updated my bbcp script to use -4
and get:

bbcp: Value not specified for '-4'.
Usage:   bbcp [Options] [Inspec] Outspec

Options: [-a [dir]] [-A] [-b [+]bf] [-B bsz] [-c [lvl]] [-C cfn] [-D] [-d path]
         [-e] [-E csa] [-f] [-F] [-g] [-h] [-i idfn] [-I slfn] [-k] [-K]
         [-L opts[@logurl]] [-l logf] [-m mode] [-n] [-N nio] [-o] [-O] [-p]
         [-P sec] [-r] [-R [args]] [-q qos] [-s snum] [-S srcxeq] [-T trgxeq]
         [-t sec] [-v] [-V] [-u loc] [-U wsz] [-w [=]wsz] [-x rate] [-y] [-z]
         [-Z pnf[:pnl]] [-4 [loc]] [-~] [-@ {copy|follow|ignore}] [-$] [-#]
[--]

I/Ospec: [user@][host:]file


Seems -4 needs an argument, but not sure what [loc] means.  Adding an IP
address changes the error message to:

bbcp: Invalid ipv4 options - 10.10.10.105

Moving the -4 to different places in the command-line changes the error
message, but never actually connects to send anything:

bbcp: i '.


Not sure how to use the -4 option.  And this package doesn't include a man page
(although I'm not sure if the previous 2012xxxx version did either).



Command-line used is:

bbcp -N io "zfs send -I ${localpool}/${localfs}/${site}@${lastsnap} \
     ${localpool}/${localfs}/${site}@${yesterday}" \
     ${user}@${remotehost}:"${zfs} recv ${recvopts} ${rempool}"
