extra sysfs attribute. In the last patch we add another
card type PCIFB2.
Michael Grzeschik (4):
arcnet: add err_skb package for package status feedback
arcnet: com20020-pci: add attribute to readback backplane status
arcnet: com20020-pci: handle backplane mode depending on card type
arcnet
We read the backplane mode of each subcard from bits 2 and 3 of the misc
register.

We add support for the PCIFB2 card from EAE.
Beside other cards, this card has the backplane mode enabled by default.

The dev_id was miscalculated. Only the two bits 4-5 are relevant for the
MA1 card. PCIARC1 and PCIFB2 use the four bits 4-7 for id selection.

In case the MACB is directly connected to a
non-mdio PHY/device, it should be possible to provide
a fixed link configuration in the DT.

We need to track the status of our queued packages. This way the driving
process knows if failed packages need to be retransmitted. For this
purpose we queue the transferred/failed packages back into the err_skb
