Based on work by Neil Turton <nturton@solarflare.com> and Kieran Mansley <kmansley@solarflare.com>. The BIU has now been verified to handle 3- and 4-dword writes within a single 128-bit register correctly. This means we can enable write- combining and only insert write barriers between writes to distinct registers. This has been observed to save about 0.5 us when pushing a TX descriptor to an empty TX queue. Signed-off-by:Ben Hutchings <bhutchings@solarflare.com>

In Falcon we can configure the fill levels of the RX data FIFO which trigger the generation of pause frames (if enabled), and we have module parameters for this. Siena does not allow the levels to be configured (or, if it does, this is done by the MC firmware and is not configurable by drivers). So far as I can tell, the module parameters are not used by our internal scripts and have not been documented (with the exception of the short parameter descriptions). Therefore, remove them and always initialise Falcon with the default values. Signed-off-by: -

This field does not exist in all MMDs we want to check, and all callers allow it to be set (fault_fatal = 0). Remove the loopback condition, as STAT2.DEVPRST should be valid regardless of any fault. Signed-off-by: -

We currently make no use of siena_nic_data::fw_{version,build} except to format the firmware version for ethtool_get_drvinfo(). Since we only read the version at start of day, this information is incorrect after an MC firmware update. Remove the cached version information and read it via MCDI whenever it is requested.

This patch converts bonding to use rx_handler. Results in cleaner __netif_receive_skb() with much less exceptions needed. Also bond-specific work is moved into bond code. Did performance test using pktgen and counting incoming packets by iptables. No regression noted. Signed-off-by:

V4: rebase to net-next-2.6 V3: remove an useless #ifdef. This patch unifies the netpoll code in bonding with netpoll code in bridge, thanks to Herbert that code is much cleaner now. Signed-off-by:

If a qeth device is set offline, data and control subchannels are cleared, which means removal of all IP Assist Primitive settings implicitly. There is no need to delete those settings explicitly. This patch removes all IP Assist invocations from offline. Signed-off-by:

This actually pointed out a (seemingly known) bug where we mangle the pfkey header in a potentially shared SKB, which is fixed here. Signed-off-by:

* Do not fail if the peer supports more or less than 3 algorithms. * Ignore unknown congestion control algorithms instead of failing. * Simplify congestion algorithm negotiation (largest is best). * Do not use a static buffer. * Fix off-by-two read overflow. * Avoid extra memory copy (in addition to skb_copy_bits()). The previous code really made no sense. Signed-off-by:

This is a patch originated with Stefano Salsano and Fabio Ludovici. It provides several alternative loss models for use with netem. This patch adds two state machine based loss models. See: http://netgroup.uniroma2.it/twiki/bin/view.cgi/Main/NetemCLGSigned-off-by:

Many users have wanted the old functionality that was lost to be able to use pfifo as inner qdisc for netem. The reason that netem could not be classful with the older API was because of the limitations of the old dequeue/requeue interface; now that qdisc API has a peek function, there is no longer a problem with using any inner qdisc's.
