* Allow setting of adaptive coalescing setting for all types of interrupt. * In msi & legacy intr, we use single interrupt for rx & tx. In this case tx_coalesce_usecs is invalid. We should use only rx_coalesce_usecs. Do not display tx_coal values for msi/intx. And do not allow user to set this as well. * Driver supports only tx/rx_coalesce_usec and adaptive coalesce settings. For other values, driver does not return error. So ethtool succeeds for unsupported values. Introduce enic_coalesce_valid() function to validate the coalescing values. * If user requests for coalesce value greater than what adaptor supports, driver uses the max value. We should at least log this. Signed-off-by:

Adaptive interrupt coalescing is available for msix. This patch adds the support for msi poll. Interface for adaptive interrupt coalescing is already added in driver. We just did not enable it for legacy intr & msi. enic_calc_int_moderation() & enic_set_int_moderation() are defined as static after enic_poll. Since enic_poll needs it, move both of these function definitions above enic_poll. No change in functionality. Signed-off-by:

Anuradha Karuppiah says: ==================== net: Introduce protodown flag. User space daemons can detect errors in the network that need to be notified to the switch device drivers. Drivers can react to this error state by doing a phy-down on the switch-port which would result in a carrier-off locally and on the directly connected switch. Doing that would prevent loops and black-holes in the network. One such use case is the multi-chassis LAG application - 1. The MLAG application runs on peer switches (say Switch0 and Switch1) synchronizing states, forwarding entries etc. between the two switches over the peer-link (this is a link directly connecting the two switches). 2. An MLAG election process designates one of the switches as a primary (for e.g. Switch0 is primary and Switch1 is secondary). 3. The peer link plays a critical role in allowing Switch0-Switch1 to function as a single LAG partner to the downstream dual-connected servers. When the peer-link between the switches goes down we have a split-brain situation. Switch0 and Switch1 are no longer in sync and are acting independently. This can result in traffic loops and traffic black-holing in the network. 4. To prevent these problems the MLAG application on the secondary switch phy-downs the MLAG ports on detecting the peer-link down. This will be seen as a carrier down on servers that are dual-connected to Switch0 and Switch1. 5. Specifically a dual-connected server will see a carrier-down on the port connected to the MLAG secondary, Switch1, and will stop using that port for traffic TX. So traffic black holing is prevented. v6 to v7: Removed some unnecessary code in response to review comments. v5 to v6: Replaced proto_flags with a simple proto_down boolean attribute in response to Dave's comments. v4 to v5: Changed the ip link display format for protodown to match the set as recommended by Stephen. v3 to v4: I have moved protodown out of IFF_XXX and introduced a separate proto_flags field with IF_PROTOF_DOWN bit being used by apps to notify switch port errors. This is in response to Stephen's comments that adding a new IFF_XXX may break user space. I have used rocker as the sample switch driver. And to test this functionality I used the qemu-rocker patch that Scott sent out in response to the v3 posting (needed to set link up/down when phy is enabled/disabled). v1 to v2: Based on Dave's suggestion I have moved out aggregating of error bits across applications to a user space framework. This patch now simply notifies an aggregated error bit to drivers enabling them to handle the error gracefully. ==================== Signed-off-by: -

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-07-14 This series contains updates to i40e and i40evf only. Joe Stringer and Jesse Gross add a ndo_features_check function to ensure that the i40e driver does not try to offload packets that exceed 80 bytes in length. Anjali adds additional stats to track flow director ATR and SB current state and flow director flush count which will help the need for verbose debug logs with respect to flow director. Also refines an error message to avoid confusion, so that it indicates what may have really happened when the init_shared_code() call possibly fails. Pawel adds new fields to the capabilities structures to handle Flex-10 device/function capabilities which is needed to support Flex-10 configs. Jesse improves the transmit performance by added a prefetch for the next transmit descriptor to be used when we know there are more coming. Mitch modifies i40evf driver to handle/allow an abundance of vectors. Currently the driver only maps transmit and receive queues to a single MSI-X vector per queue if there are exactly enough vectors for this, but if we have too many vectors, it will fail and allocate queues to vectors in a suboptimal manner. So change the condition check to allow for an excess number of vectors and won't use the extras. Also update the driver to just return success if the user attempts to set a port VLAN on a VF that already has the same port VLAN configured, instead of going through unnecessary filter removals & adds. Fix the MAC filters for VFs, which were being programmed with 0 for the VLAN value when there was no VLAN assigned. Instead, we must use -1 to indicate that no VLAN is in use. Fix the VF disable code, which was not properly cleaning up the VF and would leave the VF in an indeterminate state, so fix this by notifying the VF and then call the normal VF reset routine. Fix the logic in the driver so that MAC filters are added and removed correctly and added a check for the driver's hardware MAC address so that this filter does not get removed incorrectly. Carolyn removes incorrect #ifdef's which should not have been added in the first place and with the #ifdef's removed, make the necessary changes in the driver to resolve compile errors. Greg updates the admin queue command header defines. v2: fix indentation in patch 12 based on feedback from Sergei Shtylyov ==================== Signed-off-by: -

As an example, two boards connected back-to-back were used to measure the throughput, running the same kernel 4.1, before and after applying these patches. The netperf UDP_STREAM results below show that the bottleneck lies on the Rx side BEFORE applying the patches, and that the Rx throughput is even lower with a larger MTU. AFTER applying the patches the Rx bottleneck is gone (Rx throughput matches the Tx one) and the RX throughput is not influenced by MTU size any longer (as expected).

The eTSEC h/w is capable of scatter/gather on the receive side too if MAXFRM > MRBLR, when the allowed maximum Rx frame size is set to be greater than the maximum Rx buffer size (MRBLR). It's about time the driver makes use of this h/w capability, by supporting fixed buffer sizes and Rx S/G. The buffer size given to eTSEC for reception is fixed to 1536B (must be multiple of 64), which is the same default buffer size as before, used to accommodate standard MTU (1500B) size frames. As before, eTSEC can receive frames of up to 9600B. Individual Rx buffers are mapped to page halves (page size for eTSEC systems is 4KB). The skb is built around the first buffer of a frame (using build_skb()). In case the frame spans multiple buffers, the trailing buffers are added as Rx fragments to the skb. The last buffer in frame is marked by the L status flag. A mechanism is in place to reuse the pages owned by the driver (for Rx) for subsequent receptions. Supporting fixed size buffers allows the implementation of Rx S/G, which in turn removes the memory pressure issues the driver had before when MTU was set for jumbo frame reception. Also, in most cases, the Rx path becomes faster due to Rx page reusal, since the overhead of allocating new rx buffers is removed from the fast path. Signed-off-by:

There are several (long standing) problems about how the status field of the rx buffer descriptor (rxbd) is currently handled on the error path: - too many unnecessary 16bit reads of the two halves of the rxbd status field (32bit), also resulting in overuse of endianness convesion macros; - "bdp->status = RXBD_LARGE" makes no sense, since the "large" flag is read only (only eTSEC can write it), and trying to clear the other status bits is also error prone in this context (most of the rx status bits are read only anyway). This is fixed with a single 32bit read of the "status" field, and then the appropriate 16bit shifting is applied to access the various status bits or the rx frame length. Also corrected the use of the RXBD_LARGE flag. Additional fix: "rx_over_errors" stat is incremented instead of "rx_crc_errors" in case of RXBD_OVERRUN occurrence. Signed-off-by:

Use a more common consumer/ producer index design to improve rx buffer allocation. Instead of allocating a single new buffer (skb) on each iteration, bundle the allocation of several rx buffers at a time. This also opens the path for further memory optimizations. Remove useless check of rxq->rfbptr, since this patch touches rx pause frame handling code as well. rxq->rfbptr is always initialized as part of Rx BD ring init. Remove redundant (and misleading) 'amount_pull' parameter. Signed-off-by:

Due to an inverted conditional, the driver was marking all of its MAC filters for deletion every time set_rx_mode was called. Depending upon the timing of the calls to set_rx_mode and the processing of the admin queue, the driver would (accidentally) end up with a varying number of functional filters. Correct this logic so that MAC filters are added and removed correctly. Add a check for the driver's "hardware" MAC address so that this filter doesn't get removed incorrectly.

This patch makes the default to build IPv6 into the kernel. IPv6 now has significant traction and any remaining vestiges of IPv6 not being provided parity with IPv4 should be swept away. IPv6 is now core to the Internet and kernel. Points on IPv6 adoption: - Per Google statistics, IPv6 usage has reached 7% on the Internet and continues to exhibit an exponential growth rate https://www.google.com/intl/en/ipv6/statistics.html - Just a few days ago ARIN officially depleted its IPv4 pool - IPv6 only data centers are being successfully built (e.g. at Facebook) This patch changes the IPv6 Kconfig for IPV6. Default for CONFIG_IPV6 is set to "y" and the text has been updated to reflect the maturity of IPv6. Impact: Under some circumstances building modules in to kernel might have a performance advantage. In my testing, I did notice a very slight improvement. This will obviously increase the size of the kernel image. In my configuration I see: IPv6 as module: text data bss dec hex filename 9703666 1899288 933888 12536842 bf4c0a vmlinux IPv6 built into kernel text data bss dec hex filename 9436490 1879600 913408 12229498 ba9b7a vmlinux Which increases text size by ~270K (2.8% increase in size for me). If image size is an issue, presumably for a device which does not do IP networking (IMO we should be discouraging IPv4-only devices), IPV6 can be disabled or still built as a module. Acked-by:
