dpaa2_ni_tx_task: can't load TX buffer: error=27

[snail59]

Hello,

On a traverse ten64 , I installed FreeBSD in different ways:

• building from you sources
• building from your sources + rebasing main
• using the baremetal provided by traverse here.

The network is set as: /etc/rc.conf.d/network

ifconfig_mlxen0="DHCP"
ifconfig_mlxen0_ipv6="inet6 accept_rtadv up"

Nothing else fancy, no other network interface is configured/used.

I rsynced multiple times a 40GB file without any problem. But each time I run a verbose command such as ssh root@traverse_machine dmesg

I instantly lose connection and can see in the serial console "dpaa2_ni_tx_task: can't load TX buffer: error=27" repeatedly. Then, I can do nothing but reboot the appliance.

I've prepared and initial support for the scatter/gather Tx frames. Could you try 1e289803537dcd0b05017806002953138d6f378a?

[dsalychev]

I've re-worked dpaa2_ni_tx_task() as a part of the S/G Tx frames support and it should fail to DMA load Tx buffers less frequently, i.e. you shouldn't see "dpaa2_ni_tx_task: can't load TX buffer: error=27".

Hello, OK, I will try tonight and report the results.

So, tonight has arrived, and I did test. I can confirm that it works flawlessly, congrats @dsalychev \o/.
