The contents of /proc/net/dev is annoying to parse, because it changes whether there is a space after the "ethX:" or not. It depends upon the size of the "Receive bytes" counter, if the number is below 7 digits, then there is whitespaces else if the number is 8 digits or above there is no space between the ":" and the number. This patch changes the output to assure there is always a space between the ":" and the number. Given that all existing userspace application already need to handle the whitespaces, I see no breakage of existing tools. Signed-off-by:

This is to be used together with switch technologies, like RFC3069, that where the individual ports are not allowed to communicate with each other, but they are allowed to talk to the upstream router. As described in RFC 3069, it is possible to allow these hosts to communicate through the upstream router by proxy_arp'ing. This patch basically allow proxy arp replies back to the same interface (from which the ARP request/solicitation was received). Tunable per device via proc "proxy_arp_pvlan": /proc/sys/net/ipv4/conf/*/proxy_arp_pvlan This switch technology is known by different vendor names: - In RFC 3069 it is called VLAN Aggregation. - Cisco and Allied Telesyn call it Private VLAN. - Hewlett-Packard call it Source-Port filtering or port-isolation. - Ericsson call it MAC-Forced Forwarding (RFC Draft).

The original change overloaded null_or_orig, but doing that prevented any packet handlers that were not tied to a specific device (i.e. ptype->dev == NULL) from ever receiving any frames. The null_or_orig variable cannot be overloaded, and must be kept as NULL to prevent the frame from being ignored by packet handlers designed to accept frames on any interface. Signed-off-by:

SMSC Ethernet Transceivers (LAN88710, LAN8710, LAN8720, LAN8187, LAN8700, LAN83C185) provide a mechanism to conserve power when the device is not connected to an active link partner (Energy Detect Mode). So this patch enables the Energy Detect power-down mode for these Transceivers. Signed-off-by:

netif_device_detach() does not take the tx_lock, so it's possible that a call to sky2_xmit_frame is still in progress after netif_device_detach() is complete. Take netif_tx_lock() to make sure all transmits have stopped while we're disabling the devices and that no other CPU is still transmitting a frame after we've disabling the device. Proposed fix for "sky2 panic under load" reported by Berck E. Nash. Signed-off-by:

This patch adds the flag CAN_CTRLMODE_ONE_SHOT. It is used as mask or flag in the "struct can_ctrlmode". It allows userspace via netlink to set a CAN controller into the special "one-shot" mode. In this mode, if supported by the CAN controller, it tries only once to deliver a CAN frame and aborts it if an error (e.g.: arbitration lost) happens. Signed-off-by:

this patch removes the hlist that contains the CAN receiver filter lists. It uses the 'midlayer private' pointer ml_priv and links the filters directly to the CAN netdevice, which allows to omit the walk through the complete CAN devices hlist for each received CAN frame. This patch is tested and does not remove any locking. Signed-off-by:
