thank you for the submission, please find some process-related feedback
from me

for future submissions for intel networking please target IWL (Intel 
Wired Lan mailing list)

patches should be split into per-driver changes most of the time

please don't set "In-reply-to: v1" to v2 - just send as a standalone new
series (but link to v1 in changelog)

this is also a smallest bit above "too trivial to merge" IMO

finally this is not -net material, but -next, and -next is closed now
for PRs, and this is the only reason that warrants "v3" from you
(to:iwl, cc:netdev, after submission window reopens, ~Apr 27th)

(please collect Dan's Reviewed-by tag)
