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. Signed-off-by:

RFC5061 states: Each adaptation layer that is defined that wishes to use this parameter MUST specify an adaptation code point in an appropriate RFC defining its use and meaning. If the user has not set one - assume they don't want to sent the param with a zero Adaptation Code Point. Rationale - Currently the IANA defines zero as reserved - and 1 as the only valid value - so we consider zero to be unset - to save adding a boolean to the socket structure. Including this parameter unconditionally causes endpoints that do not understand it to report errors unnecessarily. Signed-off-by:

Some systems send SYN packets with apparently wrong RFC1323 timestamp option values [timestamp tsval=0 tsecr=0]. It might be for security reasons (http://www.secuobs.com/plugs/25220.shtml ) Linux TCP stack ignores this option and sends back a SYN+ACK packet without timestamp option, thus many TCP flows cannot use timestamps and lose some benefit of RFC1323. Other operating systems seem to not care about initial tsval value, and let tcp flows to negotiate timestamp option. Signed-off-by:

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). Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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. For the time being, I am going to disable it until I can root cause the issue. Signed-off-by:
