Does that mean you will also MFC the conversion to default
TCP mounts?  RELENG_7 still uses UDP by default.

If you MFC that, I suggest you add an entry to src/UPDATING
and possibly post a headsup to the -stable list, because
the change might affect people in unexpected ways.

Currently I happen to work at a customer with several
NetApp filers that support TCP mounts only if the -U
option is used.  UDP mounts work fine.  TCP mounts without
the -U option just hang and require a reboot.  It is
probably a bug in the filers' firmware, but said customer
cannot update the firmware for other, unrelated reasons.

Another case where people might be bitten is when there
are packet filter rules that allow UDP mounts only.

An appropriate UPDATING entry and/or a HEADSUP in -stable
might save some people's day.

Best regards
   Oliver
