From c445f200ad241b443aa7a61a5381b26f56a18f0e Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Sun, 25 Jun 2023 09:53:14 +0800 Subject: hw/net: vmxnet3: Remove the logic of padding short frames in the receive path Now that we have implemented unified short frames padding in the QEMU networking codes, remove the same logic in the NIC codes. This actually reverts commit 40a87c6c9b11ef9c14e0301f76abf0eb2582f08e.
