* macvlan: Deterministic ingress packet deliveryEric Biederman2009-03-131-13/+60
| | | | | | | | | | | | | | | | | | | | | | | | | Changing the mac address when a macvlan device is up will leave the device on the wrong hash chain making it impossible to receive packets. There is no checking of the mac address set on the macvlan. Allowing a misconfiguration to grab packets from the the underlying device or another macvlan. To resolve these problems I update the hash table of macvlans when the mac address of a macvlan changes, and when updating the hash table I verify that the new mac address is usable. The result is well defined and predictable if not perfect handling of mac vlan mac addresses. To keep the code clear I have created a set of hash table maintenance in macvlan so I am not open coding the hash function and the logic needed to update the hash table all over the place.

* macvlan: Support creating macvlans from macvlansEric Biederman2009-03-131-5/+6
| | | | | | | | | | | | | | When running in a network namespace whose only link to the outside world is a macvlan device, not being able to create another macvlan is a real pain. So modify macvlan creation to allow automatically forward a creation of a macvlan on a macvlan to become a creation of a macvlan on the underlying network device.

* smsc911x: improve EEPROM loading timeout logic in openSteve Glendinning2009-03-131-2/+2
| | | | | | | | | | | | | | | | This patch from Juha Leppanen suppresses a false warning if the eeprom load succeeds on the very last attempt. Juha> In function smsc911x_open smsc911x_reg_read+udelay can be run 50 Juha> times with timeout reaching -1, and the following if statetement Juha> does not catch the timeout and no warning is issued. Also if the Juha> 50th smsc911x_reg_read is GOOD, loop is exited with timeout as 0 Juha> and bogus warning issued. Replace testing order and --timeout Juha> instead of timeout-- and now max 50 smsc911x_reg_read's are done, Juha> with max 49 udelays.

* 8139too: allow to set mac address on running deviceJiri Pirko2009-03-131-1/+25
| | | | | | | | | | | Similar patch as for 8139cp posted yesterday, so the same comment: So far there was not a chance to set a mac address on running 8139too device. This is for example needed when you want to use this NIC as a bonding slave in bonding device in mode balance-alb. This simple patch allows it.

* forcedeth: fix irq clearing and napi spin lock changesAyaz Abdulla2009-03-101-14/+4
| | | | | | | | | | | | | | This patch clears the irqstatus register with the exact same events it has read from it. Since the read-write operation is not atomic, a new irqstatus bit could have been set in between these operations and would then be cleared accidentally. Secondly, we now don't need any spin lock protection when scheduling/completing napi poll as the isr will not execute anymore (as we turn off all interrupts now).

* forcedeth: performance changesAyaz Abdulla2009-03-101-2/+2
| | | | | | | | | | | | | This patch modifies the throughput mode poll settings to reduce the number of interrupts. This is only used by older hardware that need a timer irq in throughput mode. Secondly, this patch increases the default rx ring from 128 to 512. This drastically improves bandwidth utilization for small packets sizes i.e 512 bytes.

* forcedeth: add interrupt moderation logicAyaz Abdulla2009-03-101-31/+106
| | | | | | | | | | | | | This patch adds the logic to moderate the interrupts by changing the mode between throughput and poll. If there has been a large amount of time without any burst of network load, the code will transition to pure throughput mode (where each tx/rx/other will cause an interrupt). If bursts of network load occurs, it will transition to poll based mode to help reduce cpu utilization (it will not interrupt on each packet) while maintaining the optimum network bandwidth utilization.

* forcedeth: add new optimization modeAyaz Abdulla2009-03-101-48/+57
| | | | | | | | | | | | | A new optimization mode called Dynamic has been added. This will be mode where interrupt moderation logic will dynamically switch between pure throughput mode and poll based (called 'cpu') mode. Also, for newer chipsets, the timer irq is not needed for throughput mode. Secondly, since we are modifying the irqmask to change between modes, msix is not supported.

* forcedeth: napi - handle all processingAyaz Abdulla2009-03-101-38/+60

* forcedeth: remove overheadAyaz Abdulla2009-03-101-32/+4
| | | | | | | | | | This patch removes unnecessary overhead code. Firstly, there is no nead to mask off unwanted interrupts as we will be checking against the irqmask field anyways.

* forcedeth: save irq events for napi processingAyaz Abdulla2009-03-101-24/+23

* forcedeth: remove msix + napiAyaz Abdulla2009-03-101-21/+5
| | | | | | | | | | | This patch removes support for msix running in conjunction with napi. There has been reported issues regarding the behaviour of irqmask and generation of interrupts by the HW when in MSIX mode. When running napi, the driver is constantly turning off/on the irqmask.
