Indeed, https://www.kernel.org/doc/Documentation/SubmittingPatches
recommends submitting no more than 15 or so at once.

How about 15 from SubmittingPatches? The first 15 in the series are
all important bugfixes. Should Netanel resubmit a series with just the
bugfixes and a new cover letter? Or are you willing to consider the
first 15 of this series as posted?

You're right, the cover letter subject needs to be better. There is
only one commit submitted with the subject "increase driver version to
1.1.2." - Patch 20/20. It is logically like:

The priority is to get bug fixes to the ENA driver in 4.9. Let's focus
on the first 15.
