Hi Sven Tests after applying patches [2/6] and [3/6] are: $ ifmtu eth7 500 $ sudo test_ber -l eth7 -c 1000 -n 1000000 -f500 --no-conf ... number of sent packets = 1000000 number of received packets = 713288 number of lost packets = 286712 number of out of order packets = 0 number of bit errors = 0 total errors detected = 286712 bit error rate = 0.286712 average speed: 427.8043 Mbit/s $ ifmtu eth7 1500 $ sudo test_ber -l eth7 -c 1000 -n 1000000 -f500 --no-conf ... number of sent packets = 1000000 number of received packets = 707869 number of lost packets = 292131 number of out of order packets = 0 number of bit errors = 0 total errors detected = 292131 bit error rate = 0.292131 average speed: 431.0163 Mbit/s $ sudo test_ber -l eth7 -c 1000 -n 1000000 -f1500 --no-conf ... number of sent packets = 1000000 number of received packets = 1000000 number of lost packets = 0 number of out of order packets = 0 number of bit errors = 0 total errors detected = 0 bit error rate = 0 average speed: 646.4932 Mbit/s > Keeping in mind that Bryan has identified an issue with the above > patch, which will get fixed in v2. So YMMV. I'll perform tests with v2 as well.
