From cda4985a3ebb95f14fe3a9dc905820417baf79a5 Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Wed, 6 Nov 2019 16:03:03 +0100 Subject: net: stmmac: Fix the packet count in stmmac_rx() Currently, stmmac_rx() is counting the number of descriptors but it should count the number of packets as specified by the NAPI limit. Fix this. Fixes: ec222003bd94 ("net: stmmac: Prepare to add Split Header support") Signed-off-by: Jose Abreu Signed-off-by: David S.
