+Subject: [PATCH] net: ena: remove old adaptive interrupt moderation code from
+ ena_netdev
+Origin: https://git.kernel.org/linus/242d81fd3dd9f301b0c20564aafec8efdb2bbe5b
+Bug-Debian: https://bugs.debian.org/941291
+
+1. Out of the fields {per_napi_bytes, per_napi_packets} in struct ena_ring,
+   only rx_ring->per_napi_packets are used to determine if napi did work
+   for dim.
+   This commit removes all other uses of these fields.
+2. Remove ena_ring->moder_tbl_idx, which is not used by dim.
+3. Remove all calls to ena_com_destroy_interrupt_moderation(), since all it
+   did was to destroy the interrupt moderation table, which is removed as
+   part of removing old interrupt moderation code.
