Hello Vlad,

I intend to give proper fabric module credit where fabric module credit
is due  The original copyright from yourself + SCST developers is in
place in this patch, as well as my own copyright for the modern LLD
refactoring, forward-port and cleanups to work with mainline target
infrastructure.

I have no issues with including your's and other original author's names
for the pioneering work into the commit log for the next round of review
of PATCH #2, and am happy to make sure this is included for a future
squashed version of the series for a mainline commit.
