If the VF asks to add an invalid MAC address, tell it that instead of just using a generic return code. Change-Id: I366aff5449fa5874ad51e2734cac2a71783ab14b Signed-off-by:

Don't complain when we disable queues that are already disable, or enable them when they're already enabled. This removes a bunch of bogus log messages that we see at every VF reset. Change-Id: Ia127be572abdccc48a53d8c43f8a07b8bb920de1 Signed-off-by:

Don't keep separate functions to enable and disable queues for the VFs. Just call the existing function that everybody else uses. Remove the unused functions. Change-Id: I15db9aad64a59e502bfe1e0fdab9b347ab85c12c Signed-off-by:

Fix the VF reset flow so that it works on real hardware. After discussions with the HW team, the reset flow has been changed somewhat. - Change the i40e_reset_vf function to a void type, and fix up the callers to reflect this. - Move the MSI-X disable code to i40e_free_vf_res since it must be done every time the VF is freed, regardless of whether or not it is reset. - Ensure that the PCIe bus is quiet before polling the reset bit. - Don't clear the VFGEN_RSTAT1 register at the beginning as it is cleared by the reset. - Poll longer for the reset to be done. - Disable the queues using an existing function rather than rolling our own. - Free and reallocate the VSI after reset to avoid rx hang.

The VF reset code will be refactored in future patches. Part of that refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so the function must be moved. In order to make the future patches more readable, we perform the function move here, with no other changes. Change-Id: If6567c9c0bada6caafb2ee0227e0d9d50d05f27f Signed-off-by:

Add curly-braces on a multi-line function. While we're here we also change to return void in i40e_vsi_clear_rings() since no caller cares. Change-Id: I261fcef20e2a39e18d83ec08fdd14456131dee91 Signed-off-by:

Wake on LAN is disabled by default and will remain that way for most platforms, but there is an NVM setting that allows vendors to enable it for a port if they think they've provided the right power environment for the device. This patch adds code to check the NVM setting and enable Magic Packet use if WoL is enabled for the port. Since only Magic Packet is supported, there's not a lot of HW configuration needed.

The HMC error interrupt would generate an un-necessary message "unhandled interrupt", causing extra log spam, in addition to causing a reset that was not necessary. Prevent this issue by handling the HMC error case explicitly, and only reset if the interrupt was from some of the other causes. Change-Id: Iabd203ba1dfc26a136b638597f3e9991acfa29f3 Signed-off-by:

Running 'scripts/checkpatch.pl' on the driver files gives numerous warnings: - block comments using empty /* line; - unneeded \ at end of lines; - message string split across lines; - use of __attribute__((aligned(n))) instead of __aligned(n) macro; - use of __attribute__((packed)) instead of __packed macro. Additionally, running 'scripts/checkpatch.pl --strict' gives more complaints: - including the paragraph about writing to FSF into the heading comment; - alignment not matching open paren; - multiple assignments on one line; - use of CamelCase names; - missing {} on one of the *if* arms where another has them; - spinlock definition without a comment. While fixing these, also do some more style cleanups: - remove useless () around expressions; - add {} around multi-line *if* operator's arm; - remove space before comma; - add spaces after /* and before */; - properly align continuation lines of broken up expressions; - realign comments to the structure fields.

Tom Herbert says: ==================== ipv4: Cache dst in tunnels Version 3 of caching routes in tunnels. Addressed some comments from Eric in this series. There are two patches (variants) in the series: 1) One dst cached for each tunnel. 2) Percpu dst cache per tunnel to avoid false sharing Testing with GRE tunnels on a 32 CPU host with bnx2x (RSS support for GRE) shows a modest improvement in CPU utilization with these patches running 200 TCP_RR netperf clients.

Avoid doing a route lookup on every packet being tunneled. In ip_tunnel.c cache the route returned from ip_route_output if the tunnel is "connected" so that all the rouitng parameters are taken from tunnel parms for a packet. Specifically, not NBMA tunnel and tos is from tunnel parms (not inner packet). Signed-off-by:

Recently I updated the sctp socket option deprecation warnings to be both a bit more clear and ratelimited to prevent user processes from spamming the log file. Ben Hutchings suggested that I add the process name and pid to these warnings so that users can tell who is responsible for using the deprecated apis. This patch accomplishes that. Signed-off-by:

This adds a PHC to the mlx4_en driver. We use reader/writer spinlocks to protect the timecounter since every packet received needs to call timecounter_cycle2time() when timestamping is enabled. This can become a performance bottleneck with RSS and multiple receive queues if normal spinlocks are used. This driver has been tested with both Documentation/ptp/testptp and the linuxptp project (http://linuxptp.sourceforge.net/) on a Mellanox ConnectX-3 card. Signed-off-by:

Gratuitous arp packets are useful in switchover scenarios to update client arp tables as quickly as possible. Currently, the mac address of a neighbour is only updated after a locktime period has elapsed since the last update. In most use cases such delays are unacceptable for network admins. Moreover, the "updated" field of the neighbour stucture doesn't record the last time the address of a neighbour changed but records any change that happens to the neighbour. This is clearly a bug since locktime uses that field as meaning "addr_updated". With this observation, I was able to perpetuate a stale address by sending a stream of gratuitous arp packets spaced less than locktime apart. With this change the address is updated when a gratuitous arp is received and the arp_accept sysctl is set. Signed-off-by:
