2020-09-28igc: Clean RX descriptor error flagsAndre Guedes1-13/+1
i225 advanced receive descriptor doesn't have the following extend error bits: CE, SE, SEQ, CXE. In addition to that, the bit TCPE is called L4E in the datasheet. Clean up the code accordingly, and get rid of the macro IGC_RXDEXT_ERR_FRAME_ERR_MASK since it doesn't make much sense anymore.

2020-06-29igc: Clean up Rx timestamping logicAndre Guedes1-2/+0
Differently from I210, I225 doesn't report Rx timestamps via the TS bit Rx descriptor + RXSTMPL/RXSTMPH registers mechanism. Rx timestamps are reported in the packet buffer only, which is implemented by igc_ptp_rx_ pktstamp(). So this patch removes igc_ptp_rx_rgtstamp() and all code related to it, copied from igb driver.

2020-05-21igc: Add support for source address filters in coreAndre Guedes1-0/+2
This patch extends MAC address filter internal APIs igc_add_mac_filter() and igc_del_mac_filter(), as well as local helpers, to support filters based on source address. A new parameters 'type' is added to the APIs to indicate if the filter type is source or destination. In case it is source type, the RAH register is configured accordingly in igc_set_mac_filter_hw().

2020-05-20igc: Remove mac_table from igc_adapterAndre Guedes1-0/+1
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. So in order to simplify the MAC address filtering code and prepare it for source address support, this patch removes the mac_table from igc_adapter.

2020-05-19igc: Remove ethertype filter in PTP codeAndre Guedes1-3/+0
The driver only supports hardware timestamping for all incoming traffic (HWTSTAMP_FILTER_ALL) which is enabled via Rx Time Sync Control (TSYNCRXCTL) register already. Therefore, the ethertype filter set in in igc_ptp_set_timestamp_mode() is useless so this patch removes it.

2020-04-17igc: Fix NFC queue redirection supportAndre Guedes1-1/+4
The support for ethtool Network Flow Classification (NFC) queue redirection based on destination MAC address is currently broken in IGC. For instance, if we add the following rule, matching frames aren't enqueued on the expected rx queue. $ ethtool -N IFNAME flow-type ether dst 3c:fd:fe:9e:7f:71 queue 2 The issue here is due to the fact that igc_rar_set_index() is missing code to enable the queue selection feature from Receive Address High (RAH) register.

2020-04-17igc: Add support for ETF offloadingVinicius Costa Gomes1-0/+1
This adds support for ETF offloading for the i225 controller. For i225, the LaunchTime feature is almost a subset of the Qbv feature. The main change from the i210 is that the launchtime of each packet is specified as an offset applied to the BASET register. BASET is automatically incremented each cycle. For i225, the approach chosen is to re-use most of the setup used for taprio offloading. With a few changes: - The more or less obvious one is that when ETF is enabled, we should set add the expected launchtime to the (advanced) transmit descriptor; - The less obvious, is that when taprio offloading is not enabled, we add a dummy schedule (all queues are open all the time, with a cycle time of 1 second).

2020-04-17igc: Add support for taprio offloadingVinicius Costa Gomes1-0/+12
Adds support for translating taprio schedules into i225 cycles. This will allow schedules to run in the hardware, making the schedules enforcement more precise and saving CPU time. Right now, the only simple schedules are allowed, complex schedules are rejected. "simple" in this context are schedules that each HW queue is opened and closed only once in each cycle. Changing schedules is still not supported as well.

2020-01-06igc: Add support for TX timestampingVinicius Costa Gomes1-0/+14
This adds support for timestamping packets being transmitted. Based on the code from i210. The basic differences is that i225 has 4 registers to store the transmit timestamps (i210 has one). Right now, we only support retrieving from one register, support for using the other registers will be added later.

2020-01-06igc: Add support for RX timestampingVinicius Costa Gomes1-0/+38
This adds support for timestamping received packets. It is based on the i210, as many features of i225 work the same way. The main difference from i210 is that i225 has support for choosing the timer register to use when timestamping packets. Right now, we only support using timer 0. The other difference is that i225 stores two timestamps in the receive descriptor, right now, we only retrieve one.
