2016-04-08nfp: move filling ring information to FW configJakub Kicinski
nfp_net_[rt]x_ring_{alloc,free} should only allocate or free ring resources without touching the device. Move setting parameters in the BAR to separate functions. This will make it possible to reuse alloc/free functions to allocate new rings while the device is running. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S.

2016-04-08nfp: preallocate RX buffers early in .ndo_openJakub Kicinski
We want the .ndo_open() to have following structure: - allocate resources; - configure HW/FW; - enable the device from stack perspective. Therefore filling RX rings needs to be moved to the beginning of .ndo_open(). Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-08nfp: reorganize initial filling of RX ringsJakub Kicinski
Separate allocation of buffers from giving them to FW, thanks to this it will be possible to move allocation earlier on .ndo_open() path and reuse buffers during runtime reconfiguration. Similar to TX side clean up the spill of functionality from flush to freeing the ring. Unlike on TX side, RX ring reset does not free buffers from the ring. Ring reset means only that FW pointers are zeroed and buffers on the ring must be placed in [0, cnt - 1) positions.

2016-04-08nfp: cleanup tx ring flush and rename to resetJakub Kicinski
Since we never used flush without freeing the ring later the functionality of the two operations is mixed. Rename flush to ring reset and move there all the things which have to be done after FW ring state is cleared. While at it do some clean-ups.

2016-04-08nfp: move link state interrupt request/free callsJakub Kicinski
We need to be able to disable the link state interrupt when the device is brought down. We used to just free the IRQ at the beginning of .ndo_stop(). As we now move towards more ordered .ndo_open()/.ndo_stop() paths LSC allocation should be placed in the "allocate resource" section. Since the IRQ can't be freed early in .ndo_stop(), it is disabled instead. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-04-08nfp: correct RX buffer length calculationJakub Kicinski

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2016-04-06 This series contains updates to e1000, e1000e, igb and Kconfig. Alex fixes igb where we were casting the MAC address as __beXX and then passing it into le32_to_cpu, when we could simply cast as __lexx to maintain consistency since it is already little endian. Then enabled bulk free in transmit cleanup for igb. John Holland enables igb to pickup the MAC address from a device tree blob when CONFIG_OF has been enabled. Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where the data byte appeared duplicated. Stefan fixes up e1000 and e1000e ethtool offline tests which were calling dev_close() which causes IFF_UP to be cleared which removes teh interface routes and some addresses, so use ndo_stop() instead. Jiri Benc cleans up some old links in the Kconfig for Intel drivers where we referred to a URL which is no longer valid. I am so glad Jiri has the time in his day to spend clicking on and testing all the URL links in the the kernel.

The current URL seems to be http://www.intel.com/content/www/us/en/support/network-and-i-o/ethernet-products/000005584.html but given it's apparently constantly changing, there's no point in having it in the help text. Just keep a generic pointer to http://support.intel.com. Hopefully, this one will have a longer live. It still works, at least. Furthermore, remove a link to "the latest Intel PRO/100 network driver for Linux", this has no place in the mainline kernel and the latest Linux driver it offers is from 2006, anyway.

2016-04-06mlxsw: spectrum: Add IEEE 802.1Qbb PFC supportIdo Schimmel
Implement the appropriate DCB ops and allow a user to configure certain traffic classes as lossless. The operation configures PFC for both the egress (respecting PFC frames) and ingress (sending PFC frames) parts of the port. At egress, when a PFC frame is received for a PFC enabled priority, then all the priorities mapped to the same TC are stopped. At ingress, the priority group (PG) buffers to which the enabled PFC priorities are mapped are configured to be lossless. PFC frames will be transmitted when the Xoff threshold is crossed. The user-supplied delay parameter is used to determine the PG's size according to the following formula: PG_SIZE = PG_SIZE_LOSSY + delay * CELL_FACTOR + MTU In the worst case scenario the delay will be made up of packets that are all of size CELL_SIZE + 1, which means each packet will require almost twice its true size when buffered in the switch. We therefore multiply this value by the "cell factor", which is close to 2. Another MTU is added in case the transmitting host already started transmitting a maximum length frame when the PFC packet was received. As with PAUSE enabled ports, when the port's MTU is changed both the PGs' size and threshold are adjusted accordingly.

2016-04-06mlxsw: spectrum: Add support for PAUSE framesIdo Schimmel
When a packet ingress the switch it's placed in its assigned priority group (PG) buffer in the port's headroom buffer while it goes through the switch's pipeline. After going through the pipeline - which determines its egress port(s) and traffic class - it's moved to the switch's shared buffer awaiting transmission. However, some packets are not eligible to enter the shared buffer due to exceeded quotas or insufficient space. Marking their associated PGs as lossless will cause the packets to accumulate in the PG buffer. Another reason for packets accumulation are complicated pipelines (e.g. involving a lot of ACLs). To prevent packets from being dropped a user can enable PAUSE frames on the port. This will mark all the active PGs as lossless and set their size according to the maximum delay, as it's not configured by user. +----------------+ + | | | | | | | | | | | | | | | | | | Delay | | | | | | | | | | | | | | | Xon/Xoff threshold +----------------+ + | | | | | | 2 * MTU | | | +----------------+ + The delay (612 [Cells]) was calculated according to worst-case scenario involving maximum MTU and 100m cables. After marking the PGs as lossless the device is configured to respect incoming PAUSE frames (Rx PAUSE) and generate PAUSE frames (Tx PAUSE) according to user's settings. Whenever the port's headroom configuration changes we take into account the PAUSE configuration, so that we correctly set the PG's type (lossy / lossless), size and threshold. This can happen when: a) The port's MTU changes, as it directly affects the PG's size. b) A PG is created following user configuration, by binding a priority to it. Note that the relevant SUPPORTED flags were already mistakenly set by the driver before this commit.
