bda6a15a0d 8139too: allow to set mac address on running device
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.

6fc791ee63 sctp: add Adaptation Layer Indication parameter only when it's set
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.

fc1ad92dfc tcp: allow timestamps even if SYN packet has tsval=0
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.

1b2bb76f57 forcedeth: fix irq clearing and napi spin lock changes
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).

512 bytes.

4145ade2bb forcedeth: add interrupt moderation logic
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.
