Manpage is checked with both igor and mandoc and gives no formatting errors, so I hope everything is ok now.

Regarding the licensing issue: I wanted to contact the NetFPGA community just in case and got a response (in the private github repository https://github.com/NetFPGA/NetFPGA-SUME-live/issues/55) :
"quoting a colleague and reflecting my own thoughts…. my intuition is
that if we leave the ACKs between the copyrights and the license
header, they are more likely to be maintained by people copying and
pasting. In the middle is the conventional place to put sponsor ACKs in
my experience, although I’m not sure if that’s the reason (it’s what
I’ve seen in FreeBSD and elsewhere). But maybe there are good reasons
to move it ..?"
