This is a bug since we don't > want the queue ring to be smaller than ENA_MIN_RING_SIZE > > In this commit we change the loop's termination condition to look at the > queue size of the next iteration instead of that of the current one, > so that the minimal queue size again becomes ENA_MIN_RING_SIZE. > > Fixes: eece4d2ab9d2 ("net: ena: add ethtool function for changing io queue sizes") > > Signed-off-by: Arthur Kiyanovski <akiyano@...zon.com> > Signed-off-by: Sameeh Jubran <sameehj@...zon.com> Applied, thank you.
