fc4 was removed in October 2007 with this commit:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h\x1ecd3902c6e16c2445165b872c49e73770b72da7

Yep, I removed it.  Resurrecting it will be quite a task.  Best of luck.
I'm willing to answer questions (please cc linux-scsi), but not do
the work.

I'm OK with that.  According to http://en.wikipedia.org/wiki/Sun_Enterprise
they haven't been produced since 2001.  I don't mind keeping support
for old products in Linux, but the fc4 layer was getting in the way
of improving the SCSI subsystem for current and future hardware.
That's not acceptable, so with no maintainer for the fc4 layer, the
only option was to remove it.  If you'd like to become fc4 maintainer,
or can find someone else to do it for you, it can go back in, no problem.
