CVE-2021-20257 / rh#1930087

An infinite loop issue was found in the e1000 NIC emulator of the QEMU. It occurs while processing transmit (tx) descriptors in process_tx_desc, if various descriptor fields are initialised with invalid values. A guest may use this flaw to consume cpu cycles on the host resulting in DoS scenario.
