The following configuration will 81 * be retained: 82 * 83 * - MTU 84 * - flow control settings 85 * - receive mode configuration (promiscuous mode, all-multicast m= ode, 86 * hardware checksum mode, RSS/VMDq settings etc.) 87 * - VLAN filtering configuration 88 * - default MAC address 89 * - MAC addresses supplied to MAC address array 90 * - flow director filtering mode (but not filtering rules) 91 * - NIC queue statistics mappings defines that RSS settings must be retained across restart. Example log from dpdk-ethdev-ts tests available [1]. Lines below are lines = in the log. Steps to reproduce should be trivial and as far as I know testpmd has all required functionality:=20 - configure more than 1 Rx queue,=20 - start port (line 38), - update reta (lines 41 and 43), - stop (line 72), - start again (line 74), - read reta (line 77) and compare (example log shows that RETA is reset to default). Obviously update should not match default configuration.
