[PATCH] rtl8193: switch to use qemu_receive_packet() for loopback

From: Alexander Bulekov
Subject: [PATCH] rtl8193: switch to use qemu_receive_packet() for loopback
Date: Fri, 26 Feb 2021 13:47:53 -0500

This patch switches to use qemu_receive_packet() which can detect
reentrancy and return early.

Although it's not a nc->info->receive() call, maybe this can also go in
this series?
