commit 7b7a2bbb (atl1: Remove unneeded PM_OPS definitions) removed the definition of atl1_suspend for the !CONFIG_PM_SLEEP case. So only call atl1_suspend() when CONFIG_PM_SLEEP is defined and fix the following build error from randconfig: drivers/net/ethernet/atheros/atlx/atl1.c: In function 'atl1_shutdown': drivers/net/ethernet/atheros/atlx/atl1.c:2888:2: error: implicit declaration of function 'atl1_suspend' [-Werror=implicit-function-declaration] Reported-by:

If we can't _up() after changing the MTU, report the actual error instead of -ENOMEM. It can be really misleading cause pch_gbe is usually used in scenarios where the memory amount is really small, and thus hiding the real cause. Signed-off-by:

This patch allows setting VXLAN destination to unicast address. It allows that VXLAN can be used as peer-to-peer tunnel without multicast. v4: generalize struct vxlan_dev, "gaddr" is replaced with vxlan_rdst. "GROUP" attribute is replaced with "REMOTE". they are based by David Stevens's comments. v3: move a new attribute REMOTE into the last of an enum list based by Stephen Hemminger's comments. v2: use a new attribute REMOTE instead of GROUP based by Cong Wang's comments.

sctp: Add buffer utilization fields to /proc/net/sctp/assocs This patch adds the following fields to /proc/net/sctp/assocs output: - sk->sk_wmem_alloc as "wmema" (transmit queue bytes committed) - sk->sk_wmem_queued as "wmemq" (persistent queue size) - sk->sk_sndbuf as "sndbuf" (size of send buffer in bytes) - sk->sk_rcvbuf as "rcvbuf" (size of receive buffer in bytes) When small DATA chunks containing 136 bytes data are sent the TX_QUEUE (assoc->sndbuf_used) reaches a maximum of 40.9% of sk_sndbuf value when peer.rwnd = 0. This was diagnosed from sk_wmem_alloc value reaching maximum value of sk_sndbuf. TX_QUEUE (assoc->sndbuf_used), sk_wmem_alloc and sk_wmem_queued values are incremented in sctp_set_owner_w() for outgoing data chunks. Having access to the above values in /proc/net/sctp/assocs will provide a better understanding of SCTP buffer management. With patch applied, example output when peer.rwnd = 0 where: ASSOC ffff880132298000 is sender ffff880125343000 is receiver ASSOC SOCK STY SST ST HBKT ASSOC-ID TX_QUEUE RX_QUEUE \ ffff880132298000 ffff880124a0a0c0 2 1 3 29325 1 214656 0 \ ffff880125343000 ffff8801237d7700 2 1 3 36210 2 0 524520 \ UID INODE LPORT RPORT LADDRS <-> RADDRS HBINT INS OUTS \ 0 25108 3455 3456 *10.4.8.3 <-> *10.5.8.3 7500 2 2 \ 0 27819 3456 3455 *10.5.8.3 <-> *10.4.8.3 7500 2 2 \ MAXRT T1X T2X RTXC wmema wmemq sndbuf rcvbuf 4 0 0 72 525633 440320 524288 524288 4 0 0 0 1 0 524288 524288 Signed-off-by:Dilip Daya <dilip.daya@hp.com> Acked-by:

Implemented separate irq handling for edge and level type interrupt configuration. For edge type interrupts calls to disable_irq_nosync() and enable_irq() are removed. The at86rf230 resets the irq line only after the irq status register is read. Disabling the irq can lock the driver in situations where a irq is set by the radio while the driver is still reading the frame buffer. With irq_type configuration set to 0 the original behavior is preserverd. Additional the irq filter register is set to filter out all unused interrupts and the irq status register is read in the probe function to clear the irq line. Signed-off-by:

Vlad Yasevich says: ==================== Current dev_[uc|mc]_addr_sync() API currently correctly syncs the addresses to the first device. Any subsequent calls to sync will not do anything since the synched variable will be set. This variable is used as an optimization to skip over addresses that have been synched. There are some devices (ex: team) that attempt to do the above. There is other work in progress that needs to above to work corretly. The short series introduces dev_[uc|mc]_addr_synch_multiple() that allows multiple calls to sync to multiple different devices. Original API is left alone and still has the limitation. ==================== Signed-off-by: -

Team drivers attempts to sync addresses to each of the port devices; however, the current api doesn't really perform the sync for any device after the first one. Switch to using the new api that will actually sync the addresses to all ports. CC: Jiri Pirko <jiri@resnulli.us> Signed-off-by:

The current implementation of dev_uc_sync/unsync() assumes that there is a strict 1-to-1 relationship between the source and destination of the sync. In other words, once an address has been synced to a destination device, it will not be synced to any other device through the sync API. However, there are some virtual devices that aggreate a number of lower devices and need to sync addresses to all of them. The current API falls short there. This patch introduces a new dev_uc_sync_multiple() api that can be called in the above circumstances and allows sync to work for every invocation. CC: Jiri Pirko <jiri@resnulli.us> Signed-off-by:

There is actually no need to keep this member in the structure, because after init it's always 1 anyway, thus always kfree called. This seems to be an ancient leftover from the very initial implementation from 2.5 times. Only in case the initialization of an association fails, we leave base.malloced as 0, but we nevertheless kfree it in the error path in sctp_association_new(). Signed-off-by:

Currently, sock_tx_timestamp() always returns 0. The comment that describes the sock_tx_timestamp() function wrongly says that it returns an error when an invalid argument is passed (from commit 20d49473, ``net: socket infrastructure for SO_TIMESTAMPING'').

As network adapters supporting PTP are becoming more common, machines with many NICs suddenly have many PHCs, too. The current limit of eight /dev/ptp* char devices (and thus, 8 network interfaces with PHC) is insufficient. Let the ptp driver allocate the char devices dynamically. Tested with 28 PHCs, removing and re-adding some of them. Thanks to Ben Hutchings for advice leading to simpler and cleaner patch. Signed-off-by:

I noticed that TSQ (TCP Small queues) was less effective when TSO is turned off, and GSO is on. If BQL is not enabled, TSQ has then no effect. It turns out the GSO engine frees the original gso_skb at the time the fragments are generated and queued to the NIC. We should instead call the tcp_wfree() destructor for the last fragment, to keep the flow control as intended in TSQ. This effectively limits the number of queued packets on qdisc + NIC layers.
