2020-07-01ixgbe: Cleanup unneeded delay in ethtool testJeff Kirsher1-4/+1
There is a 4 seconds delay in ixgbe_diag_test() that is holding up other ioctls such as SIOCGIFCONF that Oracle database applications use. One of Oracle's product runs "ethtool -t ethX online" periodically for system monitoring and that is impacting database applications that use SIOCGIFCONF at that same time. This 4 second delay was needed in out early 1GbE parts to give the PHY time to recover from a reset. This code was carried forward to the 10 GbE driver even it was not needed for the supported PHYs in the ixgbe driver.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher1-2/+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.

2019-06-26ixgbe: Check DDM existence in transceiver before accessMauro S. M. Rodrigues1-1/+2
Some transceivers may 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. Currently, due to not checking this bit ixgbe fails trying 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. This issue was noticed using a Mellanox Passive DAC PN 01FT738. The eeprom data was confirmed by Mellanox as correct and present in other Passive DACs in from other manufacturers.

This change is meant to allow us to take completion time into account when disabling queues. Previously we were just working with hard coded values for how long we should wait. This worked fine for the standard case where completion timeout was operating in the 50us to 50ms range, however on platforms that have higher completion timeout times this was resulting in Rx queues disable messages being displayed as we weren't waiting long enough for outstanding Rx DMA completions.

2018-06-12treewide: Use array_size() in vmalloc()Kees Cook1-1/+1
The vmalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vmalloc(a * b) with: vmalloc(array_size(a, b)) as well as handling cases of: vmalloc(a * b * c) with: vmalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vmalloc(4 * 1024) though any constants defined via macros get caught up in the conversion.

2017-10-09ixgbe: add counter for times Rx pages gets allocated, not recycledJesper Dangaard Brouer1-0/+1
The ixgbe driver have page recycle scheme based around the RX-ring queue, where a RX page is shared between two packets. Based on the refcnt, the driver can determine if the RX-page is currently only used by a single packet, if so it can then directly refill/recycle the RX-slot by with the opposite "side" of the page. While this is a clever trick, it is hard to determine when this recycling is successful and when it fails. Adding a counter, which is available via ethtool --statistics as 'alloc_rx_page'. Which counts the number of times the recycle fails and the real page allocator is invoked. When interpreting the stats, do remember that every alloc will serve two packets. The counter is collected per rx_ring, but is summed and ethtool exported as 'alloc_rx_page'. It would be relevant to know what rx_ring that cannot keep up, but that can be exported later if someone experience a need for this.

Commit: fed21bcee7a5 ("ixgbe: Don't bother clearing buffer memory for descriptor rings) exposed some issues with the logic in the current implementation of ixgbe_clean_test_rings() that are being addressed in this patch: - Split the clearing of the Tx and Rx rings in separate loops. Previously both Tx and Rx rings were cleared in a rx_desc->wb.upper.length based loop which could lead to issues if for w/e reason packets were received outside of the frames transmitted for the loopback test. - Add check for IXGBE_TXD_STAT_DD to avoid clearing the rings if the transmits have not comlpeted by the time we enter ixgbe_clean_test_rings() - Exit early on ixgbe_check_lbtest_frame() failure.

2017-05-31ixgbe: Remove MAC X550EM_X 1Gbase-t led_[on|off] supportPaul Greenwalt1-0/+3
Since FW configures the PHY and MAC X550EM_X has no PHY access, led_[on|off] is not supported with the 1Gbase-t design. Removed MAC X550EM_X 1Gbase-t led_[on|off] support by setting function pointers to NULL and added NULL pointer checks. Also set init_led_link_act to NULL and added NULL pointer check.

2017-04-29ixgbe: Check for RSS key before setting valueTony Nguyen1-3/+1
The RSS key is being repopulated every time the interface is brought up regardless of whether there is an existing value. If the user sets the RSS key and the interface is brought up (e.g. reset), the user specified RSS key will be overwritten. This patch changes the rss_key to a pointer so we can check to see if the key has been populated and preserve it accordingly.

2017-04-29ixgbe: add support for XDP_TX actionJohn Fastabend1-0/+25
A couple design choices were made here. First I use a new ring pointer structure xdp_ring[] in the adapter struct instead of pushing the newly allocated XDP TX rings into the tx_ring[] structure. This means we have to duplicate loops around rings in places we want to initialize both TX rings and XDP rings. But by making it explicit it is obvious when we are using XDP rings and when we are using TX rings. Further we don't have to do ring arithmatic which is error prone. As a proof point for doing this my first patches used only a single ring structure and introduced bugs in FCoE code and macvlan code paths. Second I am aware this is not the most optimized version of this code possible. I want to get baseline support in using the most readable format possible and then once this series is included I will optimize the TX path in another series of patches.

2017-03-02ixgbe: update the rss key on h/w, when ethtool ask for itPaolo Abeni1-1/+3
Currently ixgbe_set_rxfh() updates the rss_key copy in the driver memory, but does not push the new value into the h/w. This commit add a new helper for the latter operation and call it in ixgbe_set_rxfh(), so that the h/w rss key value can be really updated via ethtool.

2017-02-16ixgbe: Don't bother clearing buffer memory for descriptor ringsAlexander Duyck1-1/+10
This patch makes it so that we don't need to bother with clearing the memory out for the descriptor rings. The general idea is to only free buffers associated with buffers in use which are located between the next_to_clean and next_to_use or next_to_alloc values. Everything outside of those regions can be safely ignored since they should have no buffers associated with them. The advantage to doing things this way is that is should speed up bring-up and tear-down of the rings. Specifically we can avoid the 512 or more cycles required to memset the rings in tear-down. In the bring-up phase we then clear the memory as a part of initialization. The general idea is that the clearing in initialization can act as a prefetch of sorts for the buffer info structures so they are in the local CPU when we go to populate them. This should help to improve overall time needed to perform a suspend/resume.

2017-02-16ixgbe: Add private flag to control buffer modeAlexander Duyck1-0/+47
Since there are potential drawbacks to the new Rx allocation approach I thought it best to add a "chicken bit" so that we can turn the feature off if in the event that a problem is found. It also provides a means of validating the legacy Rx path in the event that we are forced to fall back. At some point in the future when we are convinced we don't need it anymore we might be able to drop the legacy-rx flag.

2017-02-16ixgbe: Use length to determine if descriptor is doneAlexander Duyck1-1/+1
This change makes it so that we use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. The obvious advantage is that it cuts down on reads as we don't really even need the DD bit if going from a 0 to a non-zero value on size is enough to inform us that the packet has been completed.
