2009-11-26sfc: Fix descriptor cache sizesBen Hutchings
These were accidentally undersized by a factor of 2, which limited performance. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-26macvlan: export macvlan mode through netlinkArnd Bergmann
In order to support all three modes of macvlan at runtime, extend the existing netlink protocol to allow choosing the mode per macvlan slave interface. This depends on a matching patch to iproute2 in order to become accessible in user land.

2009-11-26macvlan: implement bridge, VEPA and private modeArnd Bergmann
This allows each macvlan slave device to be in one of three modes, depending on the use case: MACVLAN_PRIVATE: The device never communicates with any other device on the same upper_dev. This even includes frames coming back from a reflective relay, where supported by the adjacent bridge. MACVLAN_VEPA: The new Virtual Ethernet Port Aggregator (VEPA) mode, we assume that the adjacent bridge returns all frames where both source and destination are local to the macvlan port, i.e. the bridge is set up as a reflective relay. Broadcast frames coming in from the upper_dev get flooded to all macvlan interfaces in VEPA mode. We never deliver any frames locally. MACVLAN_BRIDGE: We provide the behavior of a simple bridge between different macvlan interfaces on the same port. Frames from one interface to another one get delivered directly and are not sent out externally. Broadcast frames get flooded to all other bridge ports and to the external interface, but when they come back from a reflective relay, we don't deliver them again. Since we know all the MAC addresses, the macvlan bridge mode does not require learning or STP like the bridge module does. Based on an earlier patch "macvlan: Reflect macvlan packets meant for other macvlan devices" by Eric Biederman.

2009-11-26macvlan: cleanup rx statisticsArnd Bergmann
We have very similar code for rx statistics in two places in the macvlan driver, with a third one being added in the next patch. Consolidate them into one function to improve overall readability of the driver. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-26veth: move loopback logic to common locationArnd Bergmann
The veth driver contains code to forward an skb from the start_xmit function of one network device into the receive path of another device. Moving that code into a common location lets us reuse the code for direct forwarding of data between macvlan ports, and possibly in other drivers.

2009-11-26via-velocity: Re-enable transmit scatter-gather supportSimon Kagstrom
The velocity hardware can handle up to 7 memory segments. This can be turned on and off via ethtool. The support was removed in commit 83c98a8cd04dd0f848574370594886ba3bf56750 but is re-enabled and cleaned up here. It's off by default.

2009-11-26via-velocity: Change DMA_LENGTH_DEF (from the VIA driver)Simon Kagstrom
The VIA driver has changed the default for the DMA_LENGTH_DEF parameter. Together with adaptive interrupt supression and NAPI support, this improves performance quite a bit Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-26via-velocity: Implement NAPI supportSimon Kagstrom
This patch adds NAPI support for VIA velocity. The new velocity_poll function also pairs tx/rx handling twice which improves perforamance on some workloads (e.g., netperf UDP_STREAM) significantly (that part is from the VIA driver).

2009-11-26via-velocity: Add ethtool interrupt coalescing supportSimon Kagstrom
(Partially from the upstream VIA driver). Tweaking the number of frames-per-interrupt and timer-until-interrupt can reduce the amount of CPU work quite a lot. Signed-off-by: Simon Kagstrom <simon.kagstrom@netinsight.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-26via-velocity: Correct 64-byte alignment for rx buffersSimon Kagstrom
(From the VIA driver). The current code does not guarantee 64-byte alignment since it simply does int add = skb->data & 63; skb->data += add; (via skb_reserve). So for example, if the skb->data address would be 0x10, this would result in 32-byte alignment (0x10 + 0x10). Correct by adding 64 - (skb->data & 63) instead.

2009-11-24sfc: Rename efx_board::init_leds to init_phy and use for SFN4111TBen Hutchings
efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY. We want to move board initialisation into NIC probing, which is too early to use MDIO, so SFN4111T initialisation also needs to be split.

2009-11-24sfc: Use a single blink implementationBen Hutchings
Only some PHYs have firmware support for a LED blink mode, so we currently blink the others in a timer function. Since all PHYs have simple on and off modes, we don't gain anything by using multiple blink implementations. Also, since we have a process context there is no need to use a timer.

2009-11-23ssb: Fix range check in sprom writeMichael Buesch
The range check in the sprom image parser hex2sprom() is broken. One sprom word is 4 hex characters. This fixes the check and also adds much better sanity checks to the code.

2009-11-23ssb: Fix SPROM writingMichael Buesch
The SPROM writing routines were broken since we rewrote the suspend handling on wireless devices, because SPROM writing depended on suspend.

2009-11-23iwlwifi: print limited number of event log when uCode errorWey-Yi Guy
To help iwlagn uCode debugging, event log will dump to syslog when driver detect uCode error occurred, but this only happen when compile with CONFIG_IWLWIFI_DEBUG and debug flag is enabled; which is not always the case. Also, there is another problem, if the flag is set, the entire event log buffer will be dump to syslog, it can flood the syslog and make it very difficult to debug the problem. Change the default to only dump last 20 entries of event log to syslog unless the following condition meets: 1. both compile with CONFIG_IWLWIFI_DEBUG and debug flag is enabled, and then dump the entire event buffer to syslog. 2. dump event log request from debugfs Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com> Acked-by: Ben Cahill <ben.m.cahill@intel.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

2009-11-23iwlwifi: Tell the ucode immediately when association state changesJay Sternberg
When we get a state change of associated or not, we need to tell the ucode via the RX_ON command using the filter flags. This will prevent the ucode from sending any packets when not associated, specifically not sending NULL QOS packets after a deauthentication which causes the AP to repeatedly send deauth's in some situations.
