From dd90c2e1ea0a7abdfa501e604523c23d6f77ffdd Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Mon, 23 Mar 2020 02:09:01 +0100 Subject: [PATCH] net: dwc_eth_qos: Flush the RX descriptors on init Currently the code only flushes the first RX descriptor, not every entry in the RX descriptor ring. Fix this, to make sure the DMA engine can pick the RX descriptors correctly.
