net: ena: fix retrieval of nonadaptive interrupt moderation intervals
Nonadaptive interrupt moderation intervals are assigned the value set by the user in ethtool -C divided by ena_dev->intr_delay_resolution. Therefore when the user tries to get the nonadaptive interrupt moderation intervals with ethtool -c the code needs to multiply the saved value by ena_dev->intr_delay_resolution. The current code erroneously divides instead of multiplying in ethtool -c. This patch fixes this. Signed-off-by: Arthur Kiyanovski <akiyano@amazon.com> Signed-off-by: David S.
