2010-04-13drivers: net: last_rx eliminationEric Dumazet
Network drivers do not have to update last_rx, unless they need it for their private use. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-04-13net: uninline skb_bond_should_drop()Eric Dumazet
skb_bond_should_drop() is too big to be inlined. This patch reduces kernel text size, and its compilation time as well (shrinking include/linux/netdevice.h) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-04-13Fix some #includes in CAN drivers (rebased for net-next-2.6)Hans J. Koch
In the current implementation, CAN drivers need to #include <linux/can.h> _before_ they #include <linux/can/dev.h>, which is both ugly and unnecessary. Fix this by including <linux/can.h> in <linux/can/dev.h> and remove the #include <linux/can.h> lines from drivers. Signed-off-by: Hans J. Koch <hjk@linutronix.de> Signed-off-by: David S.

2010-04-13bcm63xx_enet: do not overwrite ENET_CTL_REG valueFlorian Fainelli
bcm_enet_hw_preinit will correctly set values in ENET_CTL_REG for internal or external MII operations, however, bcm_enet_open will blindly overwrite the ENET_CTL_REG register value and thus we will loose any changes to it that were made in bcm_enet_hw_preinit, rendering external MII operations non-working. This would lead to the driver not being able to check for link availability on external PHY setups, and thus we would never get to sending packets because link was down from the driver side. This was completely un-noticed because all boards out there but BCM6338-based ones use internal phy on their enet0 interface.

dev_consume_skb and kfree_skb_clean have no users and in the case of kfree_skb_clean could cause potential build issues since I cannot find where it is defined.

2010-04-13tg3: Re-inline VLAN tags when appropriateMatt Carlson
The tg3 driver is written so that VLAN tagged packets can be accepted, even if CONFIG_VLAN_8021Q or CONFIG_VLAN_8021Q_MODULE is not defined. (Think raw interfaces.) If the device has ASF support enabled, the firmware requires the driver to enable VLAN tag stripping. If VLAN tagging is not explicitly supported by the kernel and ASF is enabled, the driver will have to reinject the VLAN tag back into the packet stream.

2010-04-13tg3: Optimize rx double copy testMatt Carlson
On a PCIX bus, the 5701 has a bug which requires the driver to double copy all rx packets. The rx code uses the rx_offset device member as a flag to determine if this workaround should take effect. The following patch will modify the rx_offset member such that this test will become less clear. The patch starts by integrating the workaround check into the packet length check. It rounds out the implementation by relaxing the workaround restrictions if the platform has efficient unaligned accesses.

2010-04-13net: sk_dst_cache RCUificationEric Dumazet
With latest CONFIG_PROVE_RCU stuff, I felt more comfortable to make this work. sk->sk_dst_cache is currently protected by a rwlock (sk_dst_lock) This rwlock is readlocked for a very small amount of time, and dst entries are already freed after RCU grace period. This calls for RCU again :) This patch converts sk_dst_lock to a spinlock, and use RCU for readers. __sk_dst_get() is supposed to be called with rcu_read_lock() or if socket locked by user, so use appropriate rcu_dereference_check() condition (rcu_read_lock_held() || sock_owned_by_user(sk)) This patch avoids two atomic ops per tx packet on UDP connected sockets, for example, and permits sk_dst_lock to be much less dirtied.

2010-04-13gianfar: Add hardware TX timestamping supportManfred Rudigier
If a packet has the skb_shared_tx->hardware flag set the device is instructed to generate a TX timestamp and write it back to memory after the frame is transmitted. During the clean_tx_ring operation the timestamp will be extracted and copied into the skb_shared_hwtstamps struct of the skb. TX timestamping is enabled by setting the tx_type to something else than HWTSTAMP_TX_OFF with the SIOCSHWTSTAMP ioctl command. It is only supported by eTSEC devices.

2010-04-13gianfar: Add hardware RX timestamping supportManfred Rudigier
The device is configured to insert hardware timestamps into all received packets. The RX timestamps are extracted from the padding alingment bytes during the clean_rx_ring operation and copied into the skb_shared_hwtstamps struct of the skb. This extraction only happens if the rx_filter was set to something else than HWTSTAMP_FILTER_NONE with the SIOCSHWTSTAMP ioctl command. Hardware timestamping is only supported for eTSEC devices. To indicate device support the new FSL_GIANFAR_DEV_HAS_TIMER flag was introduced. Signed-off-by: Manfred Rudigier <manfred.rudigier@omicron.at> Signed-off-by: David S. Miller <davem@davemloft.net>

Found by kmemleak. If request_resource() fails, we leak the struct resource we allocated to represent the IOMMU mapping area.
