+Subject: [PATCH] net: ena: fix retrieval of nonadaptive interrupt moderation
+ intervals
+Origin: https://git.kernel.org/linus/0eda847953d8dfb4b713ea62420f66157e230e13
+Bug-Debian: https://bugs.debian.org/941291
+
+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.
