Currently, the driver is able to query the device's specifications, which includes the maximum BD number of non TSO packet, so replace macro HNS3_MAX_NON_TSO_BD_NUM with the queried value, and rewrite macro HNS3_MAX_NON_TSO_SIZE whose value depends on the the maximum BD number of non TSO packet. Also, add a new parameter max_non_tso_bd_num to function hns3_tx_bd_num() and hns3_skb_need_linearized(), then they can get the maximum BD number of non TSO packet from the caller instead of calculating by themself, The note of hns3_skb_need_linearized() should be update as well.

2020-09-29octeontx2-af: cleanup KPU config dataStanislaw Kardach5-144/+301
Refactor KPU related NPC code gathering all configuration data in a structured format and putting it in one place (npc_profile.h). This increases readability and makes it easier to extend the profile configuration (as opposed to jumping between multiple header and source files). To do this: * Gather all KPU profile related data into a single adapter struct. * Convert the built-in MKEX definition to a structured one to streamline the MKEX loading. * Convert LT default register configuration into a structure, keeping default protocol settings in same file where identifiers for those protocols are defined. * Add a single point for KPU profile loading, so that its source may change in the future once proper interfaces for loading such config are in place.

2020-09-29octeontx2-af: fix LD CUSTOM LTYPE aliasingStanislaw Kardach1-2/+2
Since LD contains LTYPE definitions tweaked toward efficient NIX_AF_RX_FLOW_KEY_ALG(0..31)_FIELD(0..4) usage, the original location of NPC_LT_LD_CUSTOM0/1 was aliased with MPLS_IN_* definitions. Moving custom frame to value 6 and 7 removes the aliasing at the cost of custom frames being also considered when TCP/UDP RSS algo is configured. However since the goal of CUSTOM frames is to classify them to a separate set of RQs, this cost is acceptable.

2020-09-29PCI/PM: Rename pci_dev.d3_delay to d3hot_delayKrzysztof Wilczyński1-1/+1
PCI devices support two variants of the D3 power state: D3hot (main power present) D3cold (main power removed). Previously struct pci_dev contained: unsigned int d3_delay; /* D3->D0 transition time in ms */ unsigned int d3cold_delay; /* D3cold->D0 transition time in ms */ "d3_delay" refers specifically to the D3hot state. Rename it to "d3hot_delay" to avoid ambiguity and align with the ACPI "_DSM for Specifying Device Readiness Durations" in the PCI Firmware spec r3.2, sec 4.6.9.

2020-09-28qed/qed_ll2: Replace one-element array with flexible-array memberGustavo A. R. Silva2-14/+12
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct qed_ll2_tx_packet, instead of a one-element array and use the struct_size() helper to calculate the size for the allocations. Commit f5823fe6897c ("qed: Add ll2 option to limit the number of bds per packet") was used as a reference point for these changes. Also, it's important to notice that flexible-array members should occur last in any structure, and structures containing such arrays and that are members of other structures, must also occur last in the containing structure. That's why _cur_completing_packet_ is now moved to the bottom in struct qed_ll2_tx_queue. _descq_mem_ and _cur_send_packet_ are also moved for unification.

2020-09-28igc: Reject schedules with a base_time in the futureVinicius Costa Gomes1-2/+23
When we set the BASET registers of i225 with a base_time in the future, i225 will "hold" all packets until that base_time is reached, causing a lot of TX Hangs. As this behaviour seems contrary to the expectations of the IEEE 802.1Q standard (section 8.6.9, especially 8.6.9.4.5), let's start by rejecting these types of schedules. If this is too limiting, we can for example, setup a timer to configure the BASET registers closer to the start time, only blocking the packets for a "short" while.

2020-09-28igc: Save PTP time before a resetVinicius Costa Gomes3-3/+29
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").
