Re: looking for a well-supported network card

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

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.
