2023-12-13i40e: Fix ST code value for Clause 45Ivan Vecera1-2/+2
ST code value for clause 45 that has been changed by commit 8196b5fd6c73 ("i40e: Refactor I40E_MDIO_CLAUSE* macros") is currently wrong. The mentioned commit refactored ..MDIO_CLAUSE??_STCODE_MASK so their value is the same for both clauses. The value is correct for clause 22 but not for clause 45. Fix the issue by adding a parameter to I40E_GLGEN_MSCA_STCODE_MASK macro that specifies required value.

Function i40e_read_pba_string() is currently unused but will be used by subsequent patch to provide board ID via devlink device info. The function reads PBA block from NVM so it cannot be called during adapter reset and as we would like to provide PBA ID via devlink info it is better to read the PBA ID during i40e_probe() and cache it in i40e_hw structure to avoid a waiting for potential adapter reset in devlink info callback. So... - Remove pba_num and pba_num_size arguments from the function, allocate resource managed buffer to store PBA ID string and save resulting pointer to i40e_hw->pba_id field - Make the function void as the PBA ID can be missing and in this case (or in case of NVM reading failure) the i40e_hw->pba_id will be NULL - Rename the function to i40e_get_pba_string() to align with other functions like i40e_get_oem_version() i40e_get_port_mac_addr()... - Call this function on init during i40e_probe() Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

2023-10-05i40e: Remove circular header dependencies and fix headersIvan Vecera1-6/+1
Similarly as for ice driver [1] there are also circular header dependencies in i40e driver: i40e.h -> i40e_virtchnl_pf.h -> i40e.h Another issue is that i40e header files does not contain their own dependencies on other header files (both private and standard) so their inclusion in .c file require to add these deps in certain order to that .c file to make it compilable. Fix both issues by removal the mentioned circular dependency, by filling i40e headers with their dependencies so they can be placed anywhere in a source code. Additionally remove bunch of includes from i40e.h super header file that are not necessary and include i40e.h only in .c files that really require it.

This bit controls the behavior when a no-drop packet is blocking a TC queue. 0 – The PF driver is notified. 1 – The blocking packet is dropped and then the PF driver is notified.

2019-08-22i40e: Check if transceiver implements DDM before accessMauro S. M. Rodrigues1-0/+1
Similar to the ixgbe issue fixed in: 655c91414579 ("ixgbe: Check DDM existence in transceiver before access) i40e has the same issue when reading eeprom from SFP's module that comply with SFF-8472 but not implement the Digital Diagnostic Monitoring (DDM) interface described in it. The existence of such area is specified by bit 6 of byte 92, set to 1 if implemented. Without this patch, due to not checking this bit i40e fails to read SFP module's eeprom with the follow message: ethtool -m enP51p1s0f0 Cannot get Module EEPROM data: Input/output error Because it fails to read the additional 256 bytes in which it was assumed to exist the DDM data.

New device ids are created to support X710 backplane and SFP+ cards. This patch adds in i40e driver support for 2.5GbaseT and 5GbaseT speed. It's implemented by checking I40E_CAP_PHY_TYPE_2_5GBASE_T, I40E_CAP_PHY_TYPE_5GBASE_T bits from f/w and setting corresponding bits in ethtool link ksettings supported and advertising masks.

2019-04-17i40e: Implement DDP support in i40e driverAleksandr Loktionov1-0/+23
This patch introduces DDP (Dynamic Device Personalization) which allows loading profiles that change the way internal parser interprets processed frames. To load DDP profiles it utilizes ethtool flash feature. The files with recipes must be located in /var/lib/firmware directory. Afterwards the recipe can be loaded by invoking: ethtool -f <if_name> <file_name> 100 ethtool -f <if_name> - 100 See further details of this feature in the i40e documentation, or visit https://www.intel.com/content/www/us/en/architecture-and-technology/ethernet/dynamic-device-personalization-brief.html The driver shall verify DDP profile can be loaded in accordance with the rules: * Package with Group ID 0 are exclusive and can only be loaded the first. * Packages with Group ID 0x01-0xFE can only be loaded simultaneously with the packages from the same group. * Packages with Group ID 0xFF are compatible with all other packages.

Previous method for reading LLDP config was based on hard-coded offsets. It happened to work, because of structured architecture of the NVM memory. In the new approach, known as FLAT, we need to calculate the absolute address, instead of using relative values. Needed defines for memory location were added.

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.

2018-02-14i40e: Enable ADq and create queue channel/s on VFAvinash Dayanand1-1/+1
This patch enables ADq and creates queue channels on a VF. An ADq enabled VF can have up to 4 VSIs and each one of them represents a traffic class and this is termed as a queue channel. Each of these VSIs can have up to 4 queues. This patch services the request for enabling ADq and adds queue channel based on the TC mqprio info provided by the user in the VF. Initially a check is made to see if spoof check is OFF, if not ADq will not be enabled. PF notifies VF for a reset in order to complete the creation of ADq resources i.e. creation of additional VSIs and allocation of queues as per TC information, all in the reset path. Steps: ====== 1. Turn off the spoof check 2. Enable ADq using tc mqprio command with or without rate limit. 3. Pass traffic. Example: ======== % ip link set dev eth0 vf 0 spoofchk off % tc qdisc add dev $iface root mqprio num_tc 4 map\ 0 0 0 0 1 1 1 1 2 2 2 2 3 3 3 3 queues\ 4@0 4@4 4@8 4@8 hw 1 mode channel Expected results: ================= 1. Total number of queues for the VF should be sum of queues of all TCs. 2. Traffic flow should be normal without errors.

2017-11-22i40e: Fix for NUP NVM image downgrade failureJacob Keller1-0/+1
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/+1
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.
