Kenneth D. Merry 08167db8d6 Turn on FC-Tape by default in the isp(4) driver. 
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.
