Set the DPF bit when PFC is enabled. This will discard PFC frames so they do not get passed up the stack. The DPF bit is set for flow control, but not priority flow control this brings pfc inline with fc. Signed-off-by:

This change makes it possible to limit the number of descriptors down to 48 per ring. The reason for this change is to address a variation on hardware errata 10 for 82546GB in which descriptors will be lost if more than 32 descriptors are fetched and the PCI-X MRBC is 512. Signed-off-by:

On SMP systems, the SMSC911x registers may be accessed by multiple CPUs and this seems to put the chip in an inconsistent state. The patch adds spinlocks to the smsc911x_reg_read, smsc911x_reg_write, smsc911x_rx_readfifo and smsc911x_tx_writefifo functions. Signed-off-by:

Hold rtnl_lock to get the right link state. While asynchronously resetting the device, hold rtnl_lock to get the right value from netif_running. If a reset is scheduled, and the device goes thru close and open, it may happen that reset and open may run in parallel. Holding rtnl_lock will avoid this. Signed-off-by:

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.

After commit ad1afb00 (vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)), bond_inet6addr_event() might be called with a NULL bond->vlgrp pointer, and a non empty bond->vlan_list. vlan_group_get_device() is dereferencing a NULL pointer. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Richard Cochran authored
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. Signed-off-by:

Richard Cochran authored
This patch adds a hook for transmit time stamps. The transmit hook allows a software fallback for transmit time stamps, for MACs lacking time stamping hardware. Using the hook will still require adding an inline function call to each MAC driver. Signed-off-by:

- 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).

'count' is unsigned. It is initialized to zero, then it can be increased multiple times, and finally it is used in such a way: >>>> count--; | | /* clear timestamp and dma mappings for remaining portion of packet */ | while (count >= 0) { | count--; | ... ^ If count is zero here (so, it was never increased), we would have a very long loop :) Signed-off-by: -
