From 86536da001c03d2bcbdb38ccdcd023e6d744f5b8 Mon Sep 17 00:00:00 2001 From: Maxime Leroy Date: Tue, 13 Aug 2019 15:29:47 +0200 Subject: [PATCH] net/vmxnet3: remove IP checksum from capabilities The vmxnet3_prep_pkts function set rte_errno to ENOTSUP for any packets having PKT_TX_IP_CHECKSUM set in ol_flags. But the vmxnet3 has DEV_TX_OFFLOAD_IPV4_CKSUM set in this tx offload capa. This issue has been introduced with the new Rx offload API. DEV_TX_OFFLOAD_IPV4_CKSUM and DEV_RX_OFFLOAD_IPV4_CKSUM has been added to the tx/rx offloads capa, but the vmxnet3 driver doesn't support it. To fix the issue, DEV_TX/RX_OFFLOAD_IPV4_CKSUM needs to be removed from tx/rx offload capa.
