Re: [PATCH v13 2/7] net/vmnet: add vmnet backends to qapi/net

Hi,

Thank you for fixing the feature availability check.

I decided to just check the series thoroughly before adding Reviewed-By,
and unfortunately ended up finding minor memory leaks and style
problems. I'm sorry for adding comments so late.

Particulalry, his patch has several 2-space indents. They should be
4-space. Reviews for other patch will shortly follow.

Regards,
Akihiko Odaki
