Same here, format string should be on the next its own line:
### net/ngbe: add Tx queue setup and release

Comment should start from /**
Also multi-line comment should be:

Some of comments above have full stop, some do not have.
Be consistent. I'd simply remove full stop everywhere to make
lines a bit shorter.
