2020-05-22ice: Fix probe/open race conditionAnirudh Venkataramanan1-10/+14
As soon as the driver registers the PF netdev, userspace utilities like NetworkManager try to bring up the associated interface. When this happens, the driver may not have finished initializing fully, resulting in a bunch of errors in the interface up flow. The driver already has a mechanism to indicate if it's not up yet; by setting the __ICE_DOWN bit in pf->state, but this bit gets cleared too early in the current flow. So clear this bit only when the driver is fully up. Also check for the same bit in the ice_open flow, and return -EBUSY if the bit is set. Also in ice_open, replace references of vsi->back with a local variable.

2020-05-22ice: 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.

2020-05-22ice: Don't reset and rebuild for Tx timeout on PFC enabled queueAvinash JD5-0/+94
When there's a Tx timeout for a queue which belongs to a PFC enabled TC, then it's not because the queue is hung but because PFC is in action. In PFC, peer sends a pause frame for a specified period of time when its buffer threshold is exceeded (due to congestion). Netdev on the other hand checks if ACK is received within a specified time for a TX packet, if not, it'll invoke the tx_timeout routine.

2020-05-22ice: Add VF promiscuous supportBrett Creeley4-2/+223
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).

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.

We are seeing a deadlock in e1000 down when NAPI is being disabled.

2020-05-20igc: Refactor ethertype filtering codeAndre Guedes3-61/+103
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.

2020-05-19igc: Use netdev log helpers in igc_ethtool.cAndre Guedes1-20/+21
In igc_ethtool.c we print log messages using dev_* helpers, generating inconsistent output with the rest of the driver. Since this is a network device driver, we should preferably use netdev_* helpers because they append the interface name to the message, helping making sense the of the logs. This patch converts all dev_* calls to netdev_*.

2020-05-19igc: add support to eeprom, registers and link self-testsVitaly Lifshits7-3/+285
Introduced igc_diag.c and igc_diag.h, these files have the diagnostics functionality of igc driver. For the time being these files are being used by ethtool self-test callbacks. Which mean that eeprom, registers and link self-tests for ethtool were implemented.

2020-05-19igc: Use netdev log helpers in igc_main.cAndre Guedes1-61/+50
In igc_main.c we print log messages using both dev_* and netdev_* helpers, generating inconsistent output. Since this is a network device driver, we should preferably use netdev_* helpers because they append the interface name to the message, helping making sense out of the logs. This patch converts all dev_* calls to netdev_*. There is only two exceptions: 1) calls wihtin igc_probe (net_device has not been registered yet) 2) calls in igc_init_module (module initialization). It also takes this opportunity to improve some messages.
