FWIW, I have a cheap rge0 at pci7 dev 0 function 0: Realtek Semiconductor 8125 10/100/1G/2.5G Ethernet (rev. 0x00) rge0: interrupting at msix5 vec 0 rge0: HW rev. Z2 rge0: Ethernet address 00:8e:25:79:05:3c
I am running -current, usually not more than a week old. As I am in the process of decommissioning this particular machine, I just transferred over NFS its useful contents over to a QNAP server, some 350 GB perhaps. I have never had problems with this particular card, with the exception of regular messages like: ... [ 691195.713018] nfs server qn4pf:/oci: not responding [ 691196.006010] nfs server qn4pf:/oci: is alive again ... This repeats constantly, but doesn't appear to cause loss of connectivity to the server. Iperf3 returns: .... $ iperf3 -c qn4pf Connecting to host qn4pf, port 5201 [ 5] local 192.168.5.15 port 64429 connected to 192.168.5.250 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 239 MBytes 2.00 Gbits/sec 0 15.8 MBytes [ 5] 1.00-2.00 sec 226 MBytes 1.89 Gbits/sec 0 24.1 MBytes [ 5] 2.00-3.00 sec 205 MBytes 1.72 Gbits/sec 0 30.6 MBytes .... at this moment (but in a different window the transfer over NFS continues at this moment, without it I get wire speeds). I also have net.inet6.ip6.dad_count=0 net.inet.tcp.sendspace=131072 net.inet.tcp.recvspace=131072 net.inet.tcp.recvbuf_auto=1 net.inet.tcp.sendbuf_auto=1 in /etc/sysctl.conf. A cheap unmanaged 8-port Zyxel MQ-108 switch lies between.
