for USB OTG-capable hardware to implement device side of USB
Mass Storage, ie pretend it's a flash drive. It's configured
in the same way as other CTL frontends, using ctladm(8)
or ctld(8). Differently from usfs(4), all the configuration
can be done without rebuilding the kernel.
Testing and review is welcome. Right now I'm still moving,
and I don't have access to my test environment, so I'm somewhat
reluctant to making larger changes to this code; on the other
hand I don't want to let it sit on Phab until my testing setup
is back, because I want to get it into 11.1-RELEASE.

It actually doesn't - "device ctl" automatically pulls in ICL, which
would normally be a part of iscsi.ko. However, doing it that way makes
iscsi.ko unloadable, and building ctl.ko without iscsi.ko (using
MODULES_OVERRIDE) results in ctl.ko that is unloadable, due to missing
symbols that would be resolved to iscsi.ko. And since the symbols
are named "icl_whatever", it's not obvious that it's iscsi.ko that's
required.
If there is a better way - let me know.
