Thanks!

I think it depends on where the issues are.

If they are addressing issues that are also present in the existing
code, then it would make sense to get those patched as the driver
stands today, because backporting them to stable would be easier.

If they are for "new" issues, given that this patch series is more
or less experimental, I would prefer to roll them into these
patches. As mentioned, when it comes to submitting these patches,
the way I've split them wouldn't make much sense, but it does
make sense for where I am with it. Hence, I'll want to resplit
the series into something better for submission than it currently
is. If you want to reply to this thread, that is fine.

There's still a few netif_carrier_off()/netif_carrier_on()s left
in the driver even after this patch series, but I think they're in
more obscure paths, but I will also want to address those as well.
