2021-03-11igc: Fix igc_ptp_rx_pktstamp()Andre Guedes
The comment describing the timestamps layout in the packet buffer is wrong and the code is actually retrieving the timestamp in Timer 1 reference instead of Timer 0. This hasn't been a big issue so far because hardware is configured to report both timestamps using Timer 0 (see IGC_SRRCTL register configuration in igc_ptp_enable_rx_timestamp() helper). This patch fixes the comment and the code so we retrieve the timestamp in Timer 0 reference as expected. This patch also takes the opportunity to get rid of the hw.mac.type check since it is not required.

2020-09-28igc: Save PTP time before a resetVinicius Costa Gomes
Many TSN features depend on the internal PTP clock, so the internal PTP jumping when the adapter is reset can cause problems, usually in the form of "TX Hangs" warnings in the driver. The solution is to save the PTP time before a reset and restore it after the reset is done. The value of the PTP time is saved before a reset and we use the difference from CLOCK_MONOTONIC from reset time to now, to correct what's going to be the new PTP time. This is heavily inspired by commit bf4bf09bdd91 ("i40e: save PTP time before a device reset").

Differently from I210, I225 doesn't report Rx timestamps via the TS bit Rx descriptor + RXSTMPL/RXSTMPH registers mechanism.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher
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.

This patch changes adapter->nfc_rule_lock type from spin_lock to mutex so we avoid unnecessary busy waiting on lock contention. A closer look at the execution context of NFC rule API users shows that all of them run in process context. The API users are: ethtool ops, igc_configure(), called when interface is brought up by user or reset workequeue thread, igc_down(), called when interface is brought down, and igc_remove(), called when driver is unloaded.

2020-05-22igc: Refactor igc_ethtool_update_nfc_rule()Andre Guedes
Current implementation of igc_ethtool_update_nfc_rule() is a bit convoluted since it handles too many things: rule lookup, deletion and addition. This patch breaks it into three functions so we simplify the code and improve code reuse. Code related to rule lookup is refactored out to a new function called igc_get_nfc_rule(). Code related to rule addition is refactored out to a new function called igc_add_nfc_rule(). This function enables the rule in hardware and adds it to the adapter's list. Code related to rule deletion is refactored out to a new function called igc_del_nfc_rule(). This function disables the rule in hardware, removes it from adapter's list, and deletes it. As a byproduct of this refactoring, igc_enable_nfc_rule() and igc_disable_nfc_rule() are moved to igc_main.c since they are not used in igc_ethtool.c anymore, and igc_restore_nfc_rules() and igc_nfc_rule_ exit() are moved around to avoid forward declaration. Also, since this patch already touches igc_ethtool_get_nfc_rule(), it takes the opportunity to remove the 'match_flags' check. Empty flags are not allowed to be added so no need to check that.

2020-05-22igc: Fix NFC rules restorationAndre Guedes
When network interface is brought up, the driver re-enables the NFC rules previously configured. However, this is done in reverse order the rules were added and hardware filters are configured differently. For example, consider the following rules: $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:AA queue 0 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:BB queue 1 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:CC queue 2 $ ethtool -N eth0 flow-type ether dst 00:00:00:00:00:DD queue 3 RAL/RAH registers are configure so filter index 1 has address ending with AA, filter index 2 has address ending in BB, and so on. If we bring the interface down and up again, RAL/RAH registers are configured so filter index 1 has address ending in DD, filter index 2 has CC, and so on. IOW, in reverse order we had before bringing the interface down. This issue can be fixed by traversing adapter->nfc_rule_list in backwards when restoring the rules. Since hlist doesn't support backwards traversal, this patch replaces it by list_head and fixes igc_restore_nfc_rules() accordingly.

2020-05-21igc: Change byte order in struct igc_nfc_filterAndre Guedes
Every time we access the 'etype' and 'vlan_tci' fields from struct igc_nfc_filter to enable or disable filters in hardware we have to convert them from big endian to host order so it makes more sense to simply have these fields in host order. The byte order conversion should take place in igc_ethtool_get_nfc_ rule() and igc_ethtool_add_nfc_rule(), which are called by .get_rxnfc and .set_rxnfc ethtool ops, since ethtool subsystem is the one who deals with them in big endian order.

2020-05-21igc: Align terms used in NFC support codeAndre Guedes
The Network Flow Classification (NFC) support code from IGC driver uses terms such as 'rule', 'filter', 'entry', 'input' interchangeably when referring to NFC rules, making it harder to follow the code. This patch renames IGC's internal APIs, structs, and variables so we stick with the term 'rule' since this is the term used in ethtool APIs. It also removes some not applicable comments along the way. No functionality is changed by this patch.

In igc_adapter we keep a sort of shadow copy of RAL and RAH registers. There is not much benefit in keeping it, at the cost of maintainability, since adding/removing MAC address filters is not hot path, and we already keep filters information in adapter->nfc_filter_list for cleanup and restoration purposes.

2020-05-19igc: Refactor ethertype filtering codeAndre Guedes
The whole ethertype filtering code is implemented in igc_ethtool.c and mixes logic from ethtool and core parts. This patch refactors it so core logic is moved to igc_main.c, aligning the ethertype filtering code organization with the rest of the filtering code from the driver (MAC address and VLAN priority). Besides moving code to igc_main.c, this patch also does some minor improvements to the code. Below are some highlights. In case all filters are already in use and the user tries to add another filter, we return -ENOSPC instead of -EINVAL so a more meaningful error code is provided. This also aligns with the behavior implemented in MAC address filtering code. With this code refactoring, 'etype_bitmap' array in struct igc_adapter and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore and are removed.

This bit is not strictly necessary since we can convey the same information as follows: queue == -1 means queue assignment is disabled, otherwise it is enabled. In addition to make the code simpler, this change fixes some awkward situations where we pass a complete misleading 'queue' value such as in igc_uc_sync().

2020-02-24intel: Replace zero-length array with flexible-array memberGustavo A. R. Silva
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
