In rare cases, reading the legacy interrupt status register can
acknowledge an event queue whose attention flag has not yet been set
in the register. Until we service this event queue it will not
generate any more interrupts. Therefore, as a secondary check, poll

Hi,
IBM EMAC driver performs device reset (drivers/net/ibm_newemac/core.c:
emac_probe() -> emac_init_phy() -> emac_reset()) before registering
appropriate net_device (emac_probe() -> register_netdev()), so
net_device name contains raw format string during EMAC reset ("eth%d").
If the case of reset timeout, emac_report_timeout_error() function is
called to report an error. The problem is this function uses net_device
name to report device related, which is not correct, as a result in the
kernel log buffer we see:
eth%d: reset timeout
The solution is to print device_node full_name instead. After applying
the patch proposed, error string is like the following:
/plb/opb/ethernet@ef600e00: reset timeout

driver now refuses to probe TBI MDIO buses as it doesn't know about
"fsl,gianfar-tbi" compatible entry, and thus _probe() fails with
-ENODEV status.
Fix this by adding "fsl,gianfar-tbi" to the list of known Gianfar
MDIO buses.

The watchdog will schedule an interrupt to help make sure queues are
cleaned in the case when an interrupt is missed, most likely due to very
high load. On 82599, there are extra interrupt registers to account for
the larger number of MSI-X vectors (64 total for 82599 vs. 18 total for
82598). These must be taken into account when performing this operation in
the watchdog.
