The message size allocated for rtnl ifinfo dumps was limited to a single page. This is not enough for additional interface info available with devices that support SR-IOV and caused a bug in which VF info would not be displayed if more than approximately 40 VFs were created per interface. Implement a new function pointer for the rtnl_register service that will calculate the amount of data required for the ifinfo dump and allocate enough data to satisfy the request. Signed-off-by:

This patch changes the way versioning is done for igb in the kernel by removing the number after the "k." It has been determined that just the "k" is sufficient to identify a kernel version and the following number was used in an inconsistent manner. Signed-off-by:

The Host Wakeup Active bit in the PHY Port General Configuration register (page 769 register 17) must be cleared after every PHY reset to prevent an unexpected wake signal from the PHY. Originally, this was accomplished by simply reading the PHY Wakeup Control register on page 800 which clears the Host Wakeup Active bit as a side-effect. Unfortunately, a hardware bug on the 82577 and 82578 PHY can cause unexpected behavior when registers on page 800 are accessed while in gigabit mode. This patch changes the remaining instances when the Host Wakeup Active bit needs to be cleared while possibly in gigabit mode by accessing the Port General Configuration register directly instead of accessing any register on page 800.

Doing a PHY page select can take a long time, relatively speaking. This can cause a significant delay when updating a number of PHY registers on the same page by unnecessarily setting the page for each PHY access. For example when going to Sx, all the PHY wakeup registers (WUC, RAR[], MTA[], SHRAR[], IP4AT[], IP6AT[], etc.) on 82577/8/9 need to be updated which takes a long time which can cause issues when suspending. This patch introduces new PHY ops function pointers to allow callers to set the page directly and do any number of PHY accesses on that page. This feature is currently only implemented for 82577, 82578 and 82579 PHYs for both the normally addressed registers as well as the special- case addressing of the PHY wakeup registers on page 800. For the latter registers, the existing function for accessing the wakeup registers has been divided up into three- 1) enable access to the wakeup register page, 2) perform the register access and 3) disable access to the wakeup register page. The two functions that enable/disable access to the wakeup register page are necessarily available to the caller so that the caller can restore the value of the Port Control (a.k.a. Wakeup Enable) register after the wakeup register accesses are done. All instances of writing to multiple PHY registers on the same page are updated to use this new method and to acquire any PHY locking mechanism before setting the page and performing the register accesses, and release the locking mechanism afterward. Some affiliated magic number cleanup is done as well. Signed-off-by:

Start the Tx queue when the interface is brought up in e1000e_up() but do not schedule the queue until link is up as detected in the watchdog task which sets netif_carrier_on. Also flush the descriptors and clean the Tx and Rx rings before resetting the hardware when bringing the interface down otherwise there is a small window where the watchdog task can be triggered with netif_carrier_off and the Tx ring not yet empty which causes an additional and unnecessary reset.

Since EXTCNF_CTRL.SWFLAG (used in the ownership arbitration of shared resources, e.g. the PHY shared between the s/w, f/w, and h/w clients) can be cleared by any of those clients, log a debug message when software attempts to clear it and it is already cleared unexpectedly. And since the swflag is cleared by a hardware reset, the driver does not need to do that, but the mutex acquired when the bit is set must still be cleared. Signed-off-by:

When repeatedly cycling Sx->S0 states with the network cable unplugged, the 82579 PHY may not initialize as expected and may require a full power cycle to recover functionality to the device. Workaround this by testing access of the PHY registers after resuming; if that returns unexpected results toggle the LANPHYPC signal to power cycle the PHY. This is implemented in the new function e1000_resume_workarounds_pchlan() which calls another new function, e1000_toggle_lanphypc_value_ich8lan(), which has been created to reduce code duplication (same functionality required by a previous workaround). Also, e1000e_disable_gig_wol_ich8lan is now e1000_suspend_workarounds_ich8lan to better reflect what it does. Signed-off-by:

The ESB2 LAN includes a debug feature that enables far-end loopback (FELB) of the SerDes/Kumeran interface. This feature is activated when receiving a sequence of symbols that includes a reserved codeword. On a perfect link, FELB would never be activated. In the presence of bit errors, there is a very small, but non-zero, probability of FELB being activated. If the FELB is activated, the SerDes link becomes non-functional and must be reset. It could also corrupt the switching tables in the switch since the ESB2 is transmitting packets with a different source MAC address. This patch disables the FELB feature. Signed-off-by:

These is also a bug, that if you modify lacp_rate via sysfs, and add new slaves in bonding, new slaves won't use the latest lacp_rate, since ad_bond_info->lacp_fast is initialized only once, in bond_3ad_initialize(). Since both struct bond_params and ad_bond_info have lacp_fast, they are duplicate and need extra synchronization. bond_3ad_bind_slave() can use bond_params->lacp_fast to initialize port. So we can just remove lacp_fast from struct ad_bond_info. Signed-off-by:

enic driver currently passes 802.1p bits to the upper layers for packets tagged with non-zero vlan ids only. This patch extends such behaviour to zero vlan tagged packets also. The patch is dependant on the following kernel patches: 1) vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet) - net-next-2.6 git commit: ad1afb00 - Available 2.6.36 and later 2) vlan: Centralize handling of hardware acceleration. - net-next-2.6 git commit: 3701e513 - Available 2.6.37 and later Signed-off-by:

CodingStyle "Chapter 12: Macros, Enums and RTL" recommends to use enums for several related constants. Internal states can be used without defining the actual value, but all values which are visible to the outside must be defined as before. Normal values are assigned as usual and flags are defined by shifts of a bit. Signed-off-by: -

When a link is saturated (re)broadcasts of OGMs are delayed. Under heavy load this delay may exceed the orig interval which leads to OGMs being dropped (the code would only accept an OGM rebroadcast if it arrived before the next OGM was broadcasted). With this patch batman-adv will also accept delayed OGMs in order to avoid a bogus influence on the routing metric. Signed-off-by:

Perf shows a relatively high rate (about 8%) race in spin_lock_irqsave() when doing netperf between external host and guest. It's mainly becuase the lock contention between the tun_do_read() and tun_xmit_skb(), so this patch do not put self into waitqueue to reduce this kind of race. After this patch, it drops to 4%.

The tun driver allocates skb's to hold data from user and then passes the data into the network stack as received data. Most network devices allocate the receive skb with routines like dev_alloc_skb() that reserves additional space for use by network protocol stack but tun does not. Because of the lack of padding, when the packet is passed through bridge netfilter a new skb has to be allocated. Signed-off-by:

During NETDEV_UP, we use symbol_get() to get the net driver's cnic probe function. This sometimes doesn't work if NETDEV_UP happens right after NETDEV_REGISTER and the net driver is still running module init code. As a result, the cnic device may not be discovered. We fix this by probing on all NETDEV events if the device's netif_running state is up. Signed-off-by:

During iSCSI connection terminations, if the target is also terminating at about the same time, the firmware may not complete the driver's request to close or reset the connection. This is fixed by handling other events (instead of the expected completion event) as an indication that the driver's request has been rejected. Signed-off-by:
