alx's Introduction

alx standalone development tree

The puropose of this development tree is to enable us to do development on alx for both BSD and Linux with a single unified repository. This enables us to synchronize fixes for both BSD and Linux. The idea is to help end typical proprietary driver development for good:

Linux support

Linux support targets the alx driver to be built in synch with linux-next.git as the base development tree. Backport kernel support is provided by utilizing the compat-drivers framework.

To build for linux you will need a few trees. We have scripts to let you get all that you need:

cd ~
git clone git://github.com/mcgrof/compat.git
cd compat
./bin/get-compat-trees

cd ~
mkdir unified/
git clone git://github.com/mcgrof/alx.git

cd alx
./make linux

Contributions

Contributions to compat follow the same mechanisms as used in the Linux kernel, this means you should provide as Singed-off-by tag as documented on the Developer's Certificate of Origin 1.1.

Submitting patches

compat and compat-drivers contributions follow the contribution model implemented by the Linux kernel. Patches or pull requests for compat and compat-drivers must have be signed-offed. If you don't sign off on them they will not accepted. This means adding a line that says "Signed-off-by: Name email" at the end of each commit, indicating that you wrote the code and have the right to pass it on as an open source patch. For exact definition of what the Signed-off-by tag is you can read the definition of the "Developer's Certificate of Origin 1.1", which you can read here:

http://gerrit.googlecode.com/svn/documentation/2.0/user-signedoffby.html

You can send patches as follows:

alx's Issues

Network interface renamed when unload/load alx

Hi,

On Ubuntu 14.04.2 when you unload and then reload the alx module, the NIC is always renamed to eth0.

On my computer, the main network interface is named p19p1 (name given by biosdevname).
When doing :
sudo rmmod alx
sudo modprobe alx
the interface is renamed to eth0.

It is a little bit annoying because the module is unload when the computer is suspended. So when resuming from suspend, the network stops working...

I found a workaround by modifying the udev rules :
sudo cp /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/10-network.rules
sudo nano /etc/udev/rules.d/10-network.rules

Changing at the end of the line :
KERNEL=="p19p1", NAME="eth0"

And by modifying /etc/network/interfaces :

auto p19p1

iface p19p1 inet dhcp

auto eth0
iface eth0 inet dhcp

But I think more investigation is needed to make it works ot of the box

Any idea how to handle this?

This error floods the log file until the PC crashes

Error:
alx 0000:08:00.0 enp8s0: fatal interrupt 0x4019607, resetting

I'm using Ubuntu 16.04, as of now I've tried multiple kernels with the same result:

4.6.4
4.4.15
4.4.0

Seems to happen randomly.

alx swaps VLAN Bytes

Using alx with 8021q (vlan) gives some serious issues.
For example:
Incoming Packets, tagged with VLAN 2 (0x0002) are treated as VLAN 512 (0x0200).
If sending packets tagged with VLAN 2 (0x0002) the packets are correctly leaving the AR8161 NIC.

Correct working Side:

ping 192.168.0.50 -I eth0.2

tcpdump -vv -ttt -e -n -i eth0

xx:xx:xx:xx:xx:xx > xx:xx:xx:xx:xx:xx, ethertype 802.1Q (0x8100), vlan 2, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 0, offset 0, flags [DF], proto ICMP (1), length 84)
    192.168.0.1 > 192.168.0.50: ICMP echo request

ALX-Side:

tcpdump -vv -ttt -e -n -i alx0

xx:xx:xx:xx:xx:xx > ff:ff:ff:ff:ff:ff, ethertype 802.1Q (0x8100), vlan 512, p 0, ethertype ARP, Ethernet (len 6), IPv4 (len 4), Request who-has 192.168.0.50 tell 192.168.0.1

Driver failing to shutdown for Suspend and Hibernate in Ubuntu 13.04 3.8.0 kernel

Ubuntu has an open bug for a failure to shut down, using the 3.8.0 kernel. The workaround for Ubuntu will be to unload/reload the driver.

Here's the Ubuntu bug report:
