Hello all @ linuxppc-dev,
I have been working with a team of people maintaining PowerPC
Linux for the new AmigaONE X5000/20 (a Freescale p5020 SoC based
machine).
We are trying to determine why the submitted Data Path Acceleration
Architecture (DPAA) Ethernet Driver is not fully functional with
the mainstream Linux kernels.
Here is the results from my latest tests. They were performed using
the linux-4.10.17 ppc64, since that represents when the DPAA Ethernet
code was introduced.
Similar tests, with similar results, were also performed
using the latest Linux kernels:
linux-4.15-rc5
linux-4.15-rc6
linux-4.15-rc7
(Hence the reason for falling back to test the kernel right
after the introduction of the DPAA Ethernet driver sources)
---
All Kernel builds had the DPAA Ethernet enabled in the kernel,
and are using the correct cyrus_p5020.eth.dtb device tree file
(for use on the X5000/20).
The results are quite similar for all kernels in regards to the DPAA
Ethernet.
All tested kernels setup the two Ethernet interfaces correctly
as eth0 and eth1, and pull the correct MAC addresses from U-Boot
environment variables ethaddr and eth1addr respectively.
So at this point Linux has what it believes is fully configured
hardware, waiting to have an IP Address/Netmask/Gateway
to be set and to bring the interface online.
However, all attempts to communicate with the outside world
do not make it out the physical (PHY) hardware - or do they?
** The following results were captured under linux-4.10.17 **
When I bring the interface up using a static address, in this case
192.168.1.21, I see the following (NOTE TX bytes says 154.0 KB,
while RX bytes says 0.0 B):
jamie@X5000-Linux:$ ifconfig

Checking the routing table, everything looks fine there:
jamie@X5000-Linux:$ netstat -r
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt
Iface

Attempting to PING the interface itself works:
jamie@X5000-Linux:$ ping 192.168.1.21
PING 192.168.1.21 (192.168.1.21) 56(84) bytes of data.

^C
--- 192.168.1.21 ping statistics ---
3 packets transmitted, 3 received, 0% packet loss, time 2043ms
However, attempts to PING the gateway (192.168.1.1) fail as unreachable:
jamie@X5000-Linux:$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1) 56(84) bytes of data.

^C
--- 192.168.1.1 ping statistics ---
7 packets transmitted, 0 received, +3 errors, 100% packet loss, time 6077ms
In order to take a closer look at what is going on I installed Wireshark
both on my test X5000/20 Linux install (Ubuntu 16.04.3 LTS), and on
another Linux box connected to the same network switch (in this case
at IP address 192.168.1.210)
In this test I start the capture on eth0 (X5000/20) before it is put online,
and attempt to bring it up using DHCP to obtain it's address.
What I found was that network traffic *was* being attempted over eth0.
Here is a plain text export of the transmit side (the X5000/20) that
was captured using Wireshark.
(There were more network packets being sent from the X5000/20,
however, I am only showing DHCP traffic to save space in this post):

Now, over on the external Linux machine (192.168.1.210), I setup a
Wireshark capture
which filtered for any traffic to/from the MAC address of the X5000/20's
eth0, in this case
shown as Commodor_11:11:11 (00:80:10:11:11:11) below:
This export shows only the DHCP traffic seen from outside the X5000/20,
and as you can see, a matching set of DHCP requests *do in fact* make
it to the outside network.

The odd thing here is that while the DHCP requests were broadcast to the
outside network (confirming that at least the transmit to the PHY is
working),
I could see no responses from my network's DHCP server to answer these
requests.
It is not a physical networking or routing issue, as I always get a
successful
DHCP response to the X5000/20 when I enable the Realtek 8169 interface (also
installed [PCIe card] in the X5000/20).
Since initial outgoing traffic *appears* to be working from the DPAA
Ethernet
on the X5000/20, is it possible we are missing an interrupt mapping from the
Frame Manager to catch the received data?
Any help would be appreciated. Thanks.
