2010-07-20ixgbe: properly toggling netdev feature flags when disabling FCoEYi Zou2-13/+11
When FCoE is disabled, there is a race condition that FCoE offload is turned off but the FCoE protocol driver is still queuing I/O thinking offload support still exists. This patch toggles off corresponding FCoE netdev feature flags and notify the FCoE stack first, allowing FCoE protocol stack driver to update its flags upon NETDEV_FEAT_CHANGE so no I/O will be using offload. Also, indicate FCoE offload flags in vlan_features in ixgbe_probe once and do not toggle them in ixgbe_fcoe_enable/disable so when FCoE is created on the VLAN interface, vlan_transfer_features() would properly update the VLAN netdev features flag and notify the FCoE protocol driver for NETDEV_FEAT_CHANGE.

2010-07-20ixgbe: drop support for UDP in RSS hash generationAlexander Duyck1-3/+1
This change removes UDP from the supported protocols for RSS hashing. The reason for removing this protocol is because IP fragmentation was causing a network flow to be broken into two streams, one for fragmented, and one for non-fragmented and this in turn was causing out-of-order issues.

Since struct netdev_queue tx_bytes/tx_packets/tx_dropped are already protected by _xmit_lock, its easy to convert these fields to u64 instead of unsigned long. This completes 64bit stats for devices using them (vlan, macvlan, ...) Strictly, we could avoid the locking in dev_txq_stats_fold() on 64bit arches, but its slow path and we prefer keep it simple.

2010-07-19net: support time stamping in phy devices.Richard Cochran10-1/+208
This patch adds a new networking option to allow hardware time stamps from PHY devices. When enabled, likely candidates among incoming and outgoing network packets are offered to the PHY driver for possible time stamping. When accepted by the PHY driver, incoming packets are deferred for later delivery by the driver. The patch also adds phylib driver methods for the SIOCSHWTSTAMP ioctl and callbacks for transmit and receive time stamping. Drivers may optionally implement these functions.

2010-07-19net: added a BPF to help drivers detect PTP packets.Richard Cochran1-0/+126
Certain kinds of hardware time stamping units in both MACs and PHYs have the limitation that they can only time stamp PTP packets. Drivers for such hardware are left with the task of correctly matching skbs to time stamps. This patch adds a BPF that drivers can use to classify PTP packets when needed.

2010-07-19net: preserve ifreq parameter when calling generic phy_mii_ioctl().Richard Cochran25-43/+34
The phy_mii_ioctl() function unnecessarily throws away the original ifreq. We need access to the ifreq in order to support PHYs that can perform hardware time stamping. Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl(). This is unnecessary since phylib will check the command in any case.

2010-07-19net: add driver hook for tx time stamping.Richard Cochran1-0/+21

2010-07-19vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)Pedro Garcia3-49/+86
- Without the 8021q module loaded in the kernel, all 802.1p packets (VLAN 0 but QoS tagging) are silently discarded (as expected, as the protocol is not loaded). - Without this patch in 8021q module, these packets are forwarded to the module, but they are discarded also if VLAN 0 is not configured, which should not be the default behaviour, as VLAN 0 is not really a VLANed packet but a 802.1p packet. Defining VLAN 0 makes it almost impossible to communicate with mixed 802.1p and non 802.1p devices on the same network due to arp table issues. - Changed logic to skip vlan specific code in vlan_skb_recv if VLAN is 0 and we have not defined a VLAN with ID 0, but we accept the packet with the encapsulated proto and pass it later to netif_rx. - In the vlan device event handler, added some logic to add VLAN 0 to HW filter in devices that support it (this prevented any traffic in VLAN 0 to reach the stack in e1000e with HW filter under 2.6.35, and probably also with other HW filtered cards, so we fix it here). - In the vlan unregister logic, prevent the elimination of VLAN 0 in devices with HW filter. - The default behaviour is to ignore the VLAN 0 tagging and accept the packet as if it was not tagged, but we can still define a VLAN 0 if desired (so it is backwards compatible).
