This patch overwrites number of ports for X722 devices with support for OCP PHY mezzanine. The old method with checking if port is disabled in the PRTGEN_CNF register cannot be used in this case. When the OCP is removed, ports were seen as disabled, which resulted in wrong calculation of partition id, that caused WoL to be disabled on certain ports.

2017-11-21i40e: Fix for NUP NVM image downgrade failureJacob Keller1-1/+2
Since commit 96a39aed25e6 ("i40e: Acquire NVM lock before reads on all devices") we've used the NVM lock to synchronize NVM reads even on devices which don't strictly need the lock. Doing so can cause a regression on older firmware prior to 1.5, especially when downgrading the firmware. Fix this by only grabbing the lock if we're running on an X722 device (which requires the lock as it uses the AdminQ to read the NVM), or if we're currently running 1.5 or newer firmware.

2017-10-31i40e: Enable cloud filters via tc-flowerAmritha Nambiar1-0/+189
This patch enables tc-flower based hardware offloads. tc flower filter provided by the kernel is configured as driver specific cloud filter. The patch implements functions and admin queue commands needed to support cloud filters in the driver and adds cloud filters to configure these tc-flower filters. The classification function of the filter is to direct matched packets to a traffic class. The hardware traffic class is set based on the the classid reserved in the range :ffe0 - :ffef. Match Dst MAC and route to TC0: prio 1 flower dst_mac 3c:fd:fe:a0:d6:70 skip_sw\ hw_tc 1 Match Dst IPv4,Dst Port and route to TC1: prio 2 flower dst_ip 192.168.3.5/32\ ip_proto udp dst_port 25 skip_sw\ hw_tc 2 Match Dst IPv6,Dst Port and route to TC1: prio 3 flower dst_ip fe8::200:1\ ip_proto udp dst_port 66 skip_sw\ hw_tc 2 Delete tc flower filter: Example: Flow Director Sideband is disabled while configuring cloud filters via tc-flower and until any cloud filter exists. Unsupported matches when cloud filters are added using enhanced big buffer cloud filter mode of underlying switch include: 1. source port and source IP 2. Combined MAC address and IP fields. 3. Not specifying L4 port These filter matches can however be used to redirect traffic to the main VSI (tc 0) which does not require the enhanced big buffer cloud filter support.

2017-08-27i40e: prevent snprintf format specifier truncationJacob Keller1-2/+2
Increase the size of the prefix buffer so that it can hold enough characters for every possible input. Although 20 is enough for all expected inputs, it is possible for the values to be larger than expected, resulting in a possibly truncated string. Additionally, lets use sizeof(prefix) in order to ensure we use the correct size if we need to change the array length in the future. New versions of GCC starting at 7 now include warnings to prevent truncation unless you handle the return code. At most 27 bytes can be written here, so lets just increase the buffer size even if for all expected hw->bus.* values we only needed 20.

Since commit fe0b0cd97b4f ("i40e: send correct port number to AdminQ when enabling UDP tunnels") we've correctly sent the value in host order.

2016-12-02i40e: set broadcast promiscuous mode for each active VLANJacob Keller1-0/+34
A previous workaround added to ensure receipt of all broadcast frames incorrectly set the broadcast promiscuous mode unconditionally regardless of active VLAN status. Replace this partial workaround with a complete solution that sets the broadcast promiscuous filters in i40e_sync_vsi_filters. This new method sets the promiscuous mode based on when broadcast filters are added or removed. I40E_VLAN_ANY will request a broadcast filter for all VLANs, (as we're in untagged mode) while a broadcast filter on a specific VLAN will only request broadcast for that VLAN. Thus, we restore addition of broadcast filter to the array, but we add special handling for these such that they enable the broadcast promiscuous mode instead of being sent as regular filters. The end result is that we will correctly receive all broadcast packets (even those with a *source* address equal to the broadcast address) but will not receive packets for which we don't have an active VLAN filter.

2016-10-28i40e: Fix for long link down notification timeCarolyn Wyborny1-1/+4
This patch fixes a problem where it could take a very long time (>100 msec) to print the link down notification. This problem is fixed by changing how often we update link info from fw, when link is down. Without this patch, it can take over 100msec to notify user link is down.

2016-10-28i40e: Bit test mask correctionFilip Sadowski1-1/+1
Incorrect bit mask was used for testing "get link status" response. Instead of I40E_AQ_LSE_ENABLE (which is actually 0x03) it most probably should be I40E_AQ_LSE_IS_ENABLED (which is defined as 0x01).
