2009-11-26sfc: Hold MAC lock for longer in efx_init_port()Ben Hutchings1-5/+9
Although efx_init_port() is only called at probe time and so cannot race with port reconfiguration, most of the functions it calls can expect to be called with the MAC lock held. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-11-26sfc: Treat all MAC registers as 128-bitBen Hutchings2-14/+14
Although all the defined fields in these registers are within 32 bits, they are architecturally defined as 128-bit like most other Falcon registers. In particular, we must use efx_reado() to ensure proper locking when reading MD_STAT_REG. 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 Bergmann1-6/+50
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 Bergmann1-8/+72
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 Bergmann1-29/+41
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.

2009-11-26veth: move loopback logic to common locationArnd Bergmann1-14/+3
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 Kagstrom1-30/+53
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: Implement NAPI supportSimon Kagstrom2-35/+49
This patch adds NAPI support for VIA velocity.

2009-11-26via-velocity: Add ethtool interrupt coalescing supportSimon Kagstrom2-2/+165
(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 Kagstrom1-1/+2
(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.

efx_board::init_leds was introduced as a second stage of initialisation because of the inter-dependency between the board and PHY.

Only some PHYs have firmware support for a LED blink mode, so we currently blink the others in a timer function.

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.
