Thanks for the report. I've taken note that pause frames are not functional or not implemented and will look into it.
Hello,
How can I help for fix and test it? :)
Hello to all From my side I've tried to play around with pause frames parameter: https://github.com/acooks/tn40xx-driver/blob/92c112d8481b91e67fb74774b78ef577a6948729/tn40.c#L1028
_WRITE_REG(priv, 0x12E0, 0x28); WRITE_REG(priv, regPAUSE_QUANT, 0xFFFF); WRITEREG(priv, 0x6064, 0xF);
Unfortunately without success. Has anybody idea how to fix it?
Hello to all
On my PC I use network 10G card based on tehuti + Marvell MV88X3310
On the 10G everything work fine. But when I connect my PC to another (direct connection) with Intel 82574L I'm getting a lot of retransmission. I use 10G certified cable 2 meter lengths. On the both PC installed Linux Fedora 38.
Th retransmission quite easy to reproduce with iperf3.
On the Fedora 38 (with 82574L) I'm launching iperf3 server:
iperf3 -s -i 10
On the Fedora 38 (with tehuti) client: iperf3 -c 192.168.101.73 -i 10 -t 1800
In log of iperf3 client I see a lot of retransmission:
Connecting to host 192.168.101.73, port 5201 [ 5] local 192.168.101.136 port 41950 connected to 192.168.101.73 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-10.00 sec 1.08 GBytes 927 Mbits/sec 16502 59.4 KBytes

[ 5] 30.00-40.00 sec 1.08 GBytes 926 Mbits/sec 17191 52.3 KBytes
Summary problem looks like (in case of 1G connection):
Transferring Tehuti+Marvell - > Intel 82574L: a lot of retransmission Transferring Intel 82574L -> Tehuti+Marvell: no retransmission
Looks like something wrong in case of transmit data from Tehuti + Marvell to Intel 8254L
Also I have tried other PC (with Fedora 38) and Intel I219-LM with the same result.
On Marvell I have tried 0.3.10 and 0.3.11 firmwares. But on both cases I have retransmissions.
Can anybody share the idea for this behavior? For me is really strange that 10G works ok but 1 G not.
