2014-09-05amd-xgbe-phy: Check device for current speed mode (KR/KX)Lendacky, Thomas
Since device resets can change the current mode it's possible to think the device is in a different mode than it actually is. Rather than trying to determine every place that is needed to set/save the current mode, be safe and check the devices actual mode when needed rather than trying to track it.

2014-09-05enic: Add tunable_ops support for rx_copybreakGovindarajulu Varadarajan
This patch adds support for setting/getting rx_copybreak using generic ethtool tunable. Defines enic_get_tunable() & enic_set_tunable() to get/set rx_copybreak. As of now, these two function supports only rx_copybreak. Signed-off-by: Govindarajulu Varadarajan <_govind@gmx.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-09-05enic: implement rx_copybreakGovindarajulu Varadarajan

2014-09-05net: systemport: update UMAC_CMD only when link is detectedFlorian Fainelli
When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the SYSTEMPORT hardware block, and this will cause bus errors to happen in bcm_sysport_adj_link(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case This is a similar fix to the GENET one: c677ba8b3c47650358572091ed8a6af50bfca877 ("net: bcmgenet: update UMAC_CMD only when link is detected").

2014-09-04mlx4_en: Convert the normal skb free path to dev_consume_skb_any()Rick Jones
It would appear the mlx4_en driver was still making a call to dev_kfree_skb_any() where dev_consume_skb_any() would be more appropriate. This should make dropped packet profiling/tracking easier/better over a NIC driven by mlx4_en.

This patch: - Clarifies the specific requirements of devices returning CHECKSUM_UNNECESSARY (comments in skbuff.h). - Adds csum_level field to skbuff. This is used to express how many checksums are covered by CHECKSUM_UNNECESSARY (stores n - 1). This replaces the overloading of skb->encapsulation, that field is is now only used to indicate inner headers are valid. - Change __skb_checksum_validate_needed to "consume" each checksum as indicated by csum_level as layers of the the packet are parsed. - Remove skb_pop_rcv_encapsulation, no longer needed in the new csum_level model.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-08-27 This series contains updates to i40e and i40evf. Carolyn provides two patches, first changes the wording of the flow director add/remove and asynchronous failure messages to include the fd_id to try and add some way to track the operations on a given fd_id. Second adds a check during handle_link_event for unqualified modules when link is down and there is a module plugged in. Anjali provides four patches to i40e/i40evf. First update flow director messages so that a user can tell if a filter was added or deleted. Then updates the ATR policy to not auto-disable ATR when we have errors in programming. The disabling of ATR when we got programming errors was buggy and was still adding new rules and causing continuous errors. With this policy change, we flush instead when we see too many errors. In addition she adds a flow director flush counter to ethtool to help know how many times the interface had to flush and replay the flow director filter table. Updates the driver to ignores a driver perceived transmit hang if the number of descriptors pending is less than 4, and instead log a stat when this situation happens. This is because the queue progresses forward and the stack never experiences a real hang in these situations. Shannon provides three patches for i40e/i40evf, first enables the l2tsel bit on receive queue contexts that are assigned to VFs so that the VF can get the stripped VLAN tag. Then adds a max buffer size parameter to the print helper to be sure the code knows when to stop. Lastly, remove the complaint when removing the default MAC VLAN filter. This was because old firmware had an incorrect MAC VLAN filter that needed to be replaced at startup, and now newer firmware does not have this problem. So now we only add the new filter if the removal succeeded and no need to complain if the removal fails. Ashish provides a change to vsi->num_queue_pairs to equal the number that is configured by the VF. This limits the number of queues that are enabled/disabled and fixes the mismatch case for when a VF configures fewer queues than is allocated to it by the PF. ==================== Signed-off-by: David S.
