Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

* ucc_geth: Fix TX watchdog timeout handlingAnton Vorontsov2008-12-19
| | | | | | | | | | | | | | | | | | | | | | The timeout handling code is currently broken in several ways: - It calls stop() (which frees all the memory and IRQ), and then calls startup() (which won't re-request IRQ, neither it will re-init the Fast UCC structure). - It calls these routines from the softirq context, which is wrong, since stop() calls free_irq() (which might sleep) and startup() allocates things with GFP_KERNEL. - It won't soft-reset the PHY. We need the PHY reset for at least MPC8360E-MDS boards with Marvell 88E1111 PHY, the PHY won't recover from timeouts w/o the reset. So the patch fixes these problems by implementing the workqueue for the timeout handling, and there we fully re-open the device via close() and open() calls. The close/open paths do the right things, and I can see that the driver actually survive the timeouts. Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

When timeouts happen I see that these bits never get set and so the routines hang the kernel. With this patch we'll wait the graceful stop for 100 ms, and then will simply exit. There is nothing* we can do about that, but it's OK since we'll do full reset later. * Well, actually, there is also not-graceful variant for the TX stop, but specs says that we never should use it.
