From 1583ad5b5e3e75285c566b943eda7d7cbb4d2825 Mon Sep 17 00:00:00 2001 From: David Marchand Date: Tue, 18 May 2021 09:07:27 +0200 Subject: [PATCH] net/vhost: restore pseudo TSO support The net/vhost PMD does not comply with the ethdev offload API as it does not report Rx/Tx offload capabilities wrt TSO and checksum offloading. On the other hand, the net/vhost PMD lets guest negotiates TSO and checksum offloading. Changing the behavior for Rx/Tx offload flags handling won't improve/fix this situation and will break applications that might have been relying on implicit support of TSO in this driver. Revert this behavior change until we have a complete fix.
