* qeth: l3 fix len in tso hdrFrank Blaschka2010-11-28

* qeth: enable interface setup if LAN is offlineUrsula Braun2010-11-28
| | | | | | | | | | | | | | | Device initialization of a qeth device contains a STARTLAN step. This step may fail, if cable is not yet plugged in. The qeth device stays in state HARDSETUP until cable is plugged in. This prevents further preparational initialization steps of the qeth device and its network interface. This patch makes sure initialization of qeth device continues, even though cable is not yet plugged in. Once carrier is available, qeth is notified, triggers a recovery which results in a working network interface.

* ethoc: remove division from loopsJonas Bonn2010-11-28
| | | | | | | | | | | | | | | Calculating the BD entry using a modulus operation isn't optimal, especially inside the loop. This patch removes the modulus operations in favour of: i) simply checking for wrapping in the case of cur_rx ii) forcing num_tx to be a power of two and using it to mask out the entry from cur_tx The also prevents possible issues related overflow of the cur_rx and cur_tx counters.

* ethoc: rework mdio read/writeJonas Bonn2010-11-28
| | | | | | | | | | | | | | | | | | MDIO read and write were checking whether a timeout had expired to determine whether to recheck the result of the MDIO operation. Under heavy CPU usage, however, it was possible for the timeout to expire before the routine got around to be able to check a second time even, thus erroneousy returning an -EBUSY. This patch changes the the MDIO IO routines to try up to five times to complete the operation before giving up, thus lessening the dependency on CPU load. This resolves a problem whereby a ping flood would keep the CPU so busy that the above problem would manifest itself; the MDIO command to check link status would fail and the interface would erroneously be shut down.

* ethoc: rework interrupt handlingJonas Bonn2010-11-28
| | | | | | | | | | | | | | The old interrupt handling was incorrect in that it did not account for the fact that the interrupt source bits get set irregardless of whether or not their corresponding mask is set. This patch fixes that by masking off the source bits for masked interrupts. Furthermore, the handling of transmission events is moved to the NAPI polling handler alongside the reception handler, thus preventing a whole bunch of interrupts during heavy traffic.

* ethoc: Double check pending RX packetJonas Bonn2010-11-28

* ethoc: enable interrupts after napi_completeAdam Edvardsson2010-11-28

* ethoc: Add device tree configurationJonas Bonn2010-11-28
| | | | | | | | | | | | This patch adds the ability to describe ethernet devices via a flattened device tree. As device tree remains an optional feature, these bits all need to be guarded by CONFIG_OF ifdefs. MAC address is settable via the device tree parameter "local-mac-address"; however, the selection of the phy id is limited to probing, for now.

| | | | | | | | | | | | | | | | | | | | | | With the current default 'vepa' mode, a KVM guest using virtio with macvtap backend has the following limitations. - cannot change/add a mac address on the guest virtio-net - cannot create a vlan device on the guest virtio-net - cannot enable promiscuous mode on guest virtio-net To address these limitations, this patch introduces a new mode called 'passthru' when creating a macvlan device which allows takeover of the underlying device and passing it to a guest using virtio with macvtap backend. Only one macvlan device is allowed in passthru mode and it inherits the mac address from the underlying device and sets it in promiscuous mode to receive and forward all the packets.
