Hi all,
We are several Openwrt users based on the TPlink 4900 device and suffer from a
crashing gianfar driver.
We troubleshooted the problem down to the fact, that a 3.8er Linux kernel is
working, and a v3.10 crashes, but there is
no reproducable case
(runt frames or even frames
with RX error detected at PHY level) during controller reset,
the controller might fail to indicate Rx reset (GRS) completion.

ust dead code, and no
one asked for it so far.
For the Tx queues, multi-queue support (more than 1 Tx queue
per CPU) could be revisited by adding tc MQPRIO support, but
again, one has to consider that there are only 2 interrupt lines.
So the NAPI poll routine would have to service multiple Tx rings
These are very old properties that were used by the "gianfar" ethernet
driver. They don't have documented bindings and are obsolete.
