Blackfin EMAC driver: add function to change the MAC address
Alex Landau writes in the forums:
Previously, changing the MAC address (e.g. via ifconfig) resulted
in a generic function to be called that only changed a variable in
memory. This patch also updated the Blackfin MAC address registers
to filter the correct new MAC.

- One time de assert the interrupts by writing all F's to the general_int_mask
register instead of de asserting by clearing the source of interrupts with
multiple writes which causes loss of interrupts (race conditions). It is
entirely possible that before the driver has a chance to mask the asserted
alarm bit, another alarm/traffic interrupt bit gets asserted as well. In
this case Herc will keep the INTA line asserted and the bridge will not

[S2IO]: Handle and monitor all of the device errors and alarms
- Added support to poll entire set of device errors and alarams.
- A note on how device errors and alarms are handled:
- The adapter will automatically recover from uncorrectable ECC errors.
Packets containing corrupted data will be dropped (not transmitted) or tagged
as invalid before being passed to the host.
- The adapter cannot recover from any internal state machine errors. A state
machine error requires a device reset.
- Any internal error that could potentially result in .store trampling.
(undesirable PCI behaviour)is tagged as a "serious error". In such cases
the adapter will give up its ability to be a bus master. In this situation
the host will still be able to read internal device registers in order to
generate an error report. A device reset is necessary to return to normal
operation.
- In the event of a pcix data parity error, the adapter will automatically
disable itself. Adapter_En will automatically transition from '1' to '0' and
the adapter will enter its clean-up routine. Once the device has achieved
quiescence, an adapter reset should be performed.
- Replaced alarm_intr_handler() with s2io_handle_errors().
- Added statistic counters to monitor the alarms.

S2io: Enable all the error and alarm indications
- Added support to unmask entire set of device errors and alarams.
Alarm interrupts are generated for a myriad of purposes, ranging from
illegal operations or requests to internal state machine errors and
uncorrectable data corruption errors. In several cases the adapter can
recover gracefully from unexpected events; however, in some cases, a device
reset may be necessary. This patch handles alarms generated by all the
blocks within the device.
The adapter generates the following types of alarms:
1. Link state transitions (local/remote fault) or other link-related
problems.
2. Problems with any device peripherals, including the EEPROM, FLASH,
etc.
3. Correctable ECC errors (single-bit errors) on internal data
structures or frame data.
4. Uncorrectable ECC errors (multi-bit errors) on internal data
structures or frame data.
5. State machine errors, which indicate that internal control
structures have become corrupted.
6. PCI related errors, including parity errors or illegal transactions.
7. Other unexpected events.

* sparse/checkpatch cleanups, namespace cleanups

PS3: changed the way to handle tx skbs
The PS3 virtual network device requires a vlan tag in the sending packet
to select the destination device, ethernet port or wireless.
As the vlan tag field is in the middle of the passed data,
we should insert it into the packet data.
To avoid copying much of the packet data, the driver used two tx descriptors
for one tx skb; one descriptor was for sending a small static
buffer which contained vlan tag and copied header (two mac addresses),
one was for the residual data after the vlan field.
This patch changes the way to insert the vlan tag. By changing
netdev->hard_header_len, we can make the headroom for moving mac address
fields in the skb buffer. Then we can send one tx skb with
one tx descriptor. This also gives us a tx throughut gain of approx.
20% according to netperf results.

though there hasn't been an interrupt. Instead of setting up a dedicated

ibmveth: Enable TCP checksum offload
This patchset enables TCP checksum offload support for IPV4
on ibmveth. This completely eliminates the generation and checking of
the checksum for packets that are completely virtual and never
touch a physical network. A simple TCP_STREAM netperf run on
a virtual network with maximum mtu set yielded a ~30% increase
in throughput. This feature is enabled by default on systems that
support it, but can be disabled with a module option.
