2020-08-01ice: add useful statisticsJesse Brandeburg1-0/+4
Display and count some useful hot-path statistics. The usefulness is as follows: - tx_restart: use to determine if the transmit ring size is too small or if the transmit interrupt rate is too low. - rx_gro_dropped: use to count drops from GRO layer, which previously were completely uncounted when occurring. - tx_busy: use to determine when the driver is miscounting number of descriptors needed for an skb. - tx_timeout: as our other drivers, count the number of times we've reset due to timeout because the kernel only prints a warning once per netdev. Several of these were already counted but not displayed.

2020-07-23ice: add link lenient and default override supportPaul Greenwalt1-200/+319
Adds functions to check for link override firmware support and get the override settings for a port. The previously supported/default link mode was strict mode. In strict mode link is configured based on get PHY capabilities PHY types with media. Lenient mode is now the default link mode. In lenient mode the link is configured based on get PHY capabilities PHY types without media. This allows the user to configure link that the media does not report. Limit the minimum supported link mode to 25G for devices that support 100G, and 1G for devices that support less than 100G. Default override is only supported in lenient mode. If default override is supported and enabled, then default override values are used for configuring speed and FEC. Default override provide persistent link settings in the NVM.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher1-1/+0
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

2020-05-21ice: only drop link once when setting pauseparamsDave Ertman1-12/+0
Currently, the ice driver is setting a PHY configuration, which causes a link drop, and then additionally it calls for a nway_reset, which restarts auto-negotiation on the link, which also causes a link drop. These two link events in such close timing is causing the FW to not be able to generate a link interrupt for the driver to respond to. Remove the unnecessary auto-negotiation restart from the set pauseparams flow. Also remove error path that would have performed an ice_down/ice_up as that is also unnecessary.

2020-05-21ice: Add VF promiscuous supportBrett Creeley1-0/+12
Implement promiscuous support for VF VSIs. Behaviour of promiscuous support is based on VF trust as well as the, introduced, vf-true-promisc flag. A trusted VF with vf-true-promisc disabled will be the default VSI, which means that all traffic without a matching destination MAC address in the device's internal switch will be forwarded to this VF VSI. A trusted VF with vf-true-promisc enabled will go into "true promiscuous mode". This amounts to the VF receiving all ingress and egress traffic that hits the device's internal switch. An untrusted VF will only receive traffic destined for that VF. The vf-true-promisc-support flag cannot be toggled while any VF is in promiscuous mode. This flag should be set prior to loading the iavf driver or spawning VF(s).

2020-03-21ice: store NVM version info in extracted formatJacob Keller1-6/+7
The NVM version and Option ROM version information is stored within the struct ice_nvm_ver_info structure. The data for the NVM is stored as a 2byte value with the major and minor versions each using one byte from the field. The Option ROM is stored as a 4byte value that contains a major, build, and patch number. Modify the code to immediately extract the version values and store them in a new struct ice_orom_info. Remove the now unnecessary ice_get_nvm_version function. Update ice_ethtool.c to use the new fields directly from the structured data. This reduces complexity of the code that prints these versions in ice_ethtool.c Update the macro definitions and variable names to use the term "orom" instead of "oem" for the Option ROM version. This helps increase the clarity of the Option ROM version code.

2020-02-15ice: Add support to enable/disable all Rx queues before waitingBrett Creeley1-2/+2
Currently when we enable/disable all Rx queues we do the following sequence for each Rx queue and then move to the next queue. 1. Enable/Disable the Rx queue via register write. 2. Read the configuration register to determine if the Rx queue was enabled/disabled successfully. In some cases enabling/disabling queue 0 fails because of step 2 above. Fix this by doing step 1 for all of the Rx queues and then step 2 for all of the Rx queues. Also, there are cases where we enable/disable a single queue (i.e. SR-IOV and XDP) so add a new function that does step 1 and 2 above with a read flush in between. This change also required a single Rx queue to be enabled/disabled with and without waiting for the change to propagate through hardware. Fix this by adding a boolean wait flag to the necessary functions. Also, add the keywords "one" and "all" to distinguish between enabling/disabling a single Rx queue and all Rx queues respectively.

This patch is generated using following script: EXCLUDE_FILES="include/linux/stddef.h|include/linux/kernel.h" git grep -l -e "\bFIELD_SIZEOF\b" | while read file; do if [[ "$file" =~ $EXCLUDE_FILES ]]; then continue fi sed -i -e 's/\bFIELD_SIZEOF\b/sizeof_field/g' $file; done Signed-off-by: Pankaj Bharadiya <pankaj.laxminarayan.bharadiya@intel.com> Link: https://lore.kernel.org/r/20190924105839.110713-3-pankaj.laxminarayan.bharadiya@intel.com Co-developed-by: Kees Cook <keescook@chromium.org> Signed-off-by: Kees Cook <keescook@chromium.org> Acked-by: David Miller <davem@davemloft.net> # for net
2019-11-22ice: Implement ethtool ops for channelsHenry Tieman1-0/+185
Add code to query and set the number of channels on the primary VSI for a PF. This is accessed from the 'ethtool -l' and 'ethtool -L' commands, respectively. Though the ice driver supports asymmetric queues report an IRQ vector that has both Rx and Tx queues attached and is counted as a 'combined' channel.

2019-11-22ice: Add ice_pf_to_dev(pf) macroBrett Creeley1-26/+31
We use &pf->dev->pdev all over the code. Add a simple macro to do this for us. When multiple de-references like this are being done add a local struct device variable.

2019-11-22ice: Do not use devm* functions for local usesTony Nguyen1-28/+22
In situations where we alloc and free memory within the same function do not use the devm_* variants; use regular alloc and free functions. Remove any unused vars if there are no usages after these changes. Also, replace an allocate and copy with kmemdup() and remove an unnecessary memset() to 0 after a kzalloc().

2019-11-22ice: Fix setting coalesce to handle DCB configurationBrett Creeley1-3/+10
Currently there can be a case where a DCB map is applied and there are more interrupt vectors (vsi->num_q_vectors) than Rx queues (vsi->num_rxq) and Tx queues (vsi->num_txq). If we try to set coalesce settings in this case it will report a false failure. Fix this by checking if vector index is valid with respect to the number of Tx and Rx queues configured.

2019-11-08ice: configure software LLDP in ice_init_pf_dcbPaul Greenwalt1-5/+0
Move software LLDP configuration when FW DCBX is disabled to ice_init_pf_dcb, since that is where the FW DCBX state is determined. Remove this software LLDP configuration from ice_vsi_setup and ice_set_priv_flags. Software configuration includes redirecting Rx LLDP packets up the stack, when FW DCBX is not running.

2019-11-08ice: Fix to change Rx/Tx ring descriptor size via ethtool with DCBxUsha Ketineni1-7/+7
This patch fixes the call trace caused by the kernel when the Rx/Tx descriptor size change request is initiated via ethtool when DCB is configured. ice_set_ringparam() should use vsi->num_txq instead of vsi->alloc_txq as it represents the queues that are enabled in the driver when DCB is enabled/disabled. Otherwise, queue index being used can go out of range. For example, when vsi->alloc_txq has 104 queues and with 3 TCS enabled via DCB, each TC gets 34 queues, vsi->num_txq will be 102 and only 102 queues will be enabled.

2019-11-04ice: introduce frame padding computation logicMaciej Fijalkowski1-1/+1
Take into account the underlying architecture specific settings and based on that calculate the possible padding that can be supplied. Typically, for x86 and standard MTU size we will end up with 192 bytes of headroom. This is the same behavior as our other drivers have and we can dedicate it for XDP purposes. Furthermore, introduce the Rx ring flag for indicating whether build_skb is used on particular. Based on that invoke the routines for padding calculation.
