FC-Tape provides additional link level error recovery, and is
highly recommended for tape devices. It will only be turned on for
a given target if the target supports it.
Without this setting, we default to whatever FC-Tape setting is in
NVRAM on the card.
This can be overridden by setting the following loader tunable, for
example for isp0:
hint.isp.0.nofctape=1
sys/conf/options:
Add a new kernel config option, ISP_FCTAPE_OFF, that
defaults the FC-Tape configuration to off.
sys/dev/isp/isp_pci.c:
If ISP_FCTAPE_OFF is defined, turn off FC-Tape. Otherwise,
turn it on if the card supports it.
share/man/man4/isp.4:
Add a description of FC-Tape to the isp(4) man page.
Add descriptions of the fctape and nofctape options, as well as the
ISP_FCTAPE_OFF kernel configuration option.
Add the ispfw module and kernel drivers to the suggested
configurations at the top of the man page so that users are less
likely to leave it out. The driver works well with the included
firmware, but may not work at all with whatever firmware the user
has flashed on their card.

bytes; clearly not useful, and not something we should try to attach.
As a fortuitous side effect, checking that these values are non-zero
here results in them not *becoming* zero later on the function. This
odd behaviour began with r309124 (clang 3.9.0) but is challenging to
debug; making any changes to this function whatsoever seems to affect
the llvm optimizer behaviour enough to make the unexpected zeroing of
the sector_size variable cease.
