When LLDP/DCBX change happens the i40e driver code flow tried to notify the client(s) for each of the PF VSIs. This resulted into kernel panic on the first VSI that didn't have any netdev associated to it. The DCB change notification to the client(s) should be done only once for the PF/LAN VSI where the client(s) instances have been added to. Also, move the notification call after the PF driver has made changes related to the updated DCB configuration. Signed-off-by:

Since the macaddr add and delete happens asynchronously, error messages don't easily get associated to the actual request. Here we add a bit of information to the error messages to help determine the source of the error. Change-ID: Id2d6df5287141c3579677d72d8bd21122823d79f Signed-off-by:

Remove the need for a reset when the device enters limited promiscuous mode. This was causing heartburn for people who were using VFs and bridging, since this would require all of the VFs to undergo a reset each time the PF changed its promiscuity.

Always add MAC address at the tail of the MAC filter list. Since the device's "real" MAC address is added first, it will always be at the beginning of the list. This prevents an issue where the "real" MAC filter might not get added if too many other filters are added before bringing the interface up.

Limiting qcount to pf->num_lan_msix, effectively limits the RSS queues to only use the number of CPUs, and ignore all other queues. We don't want to do this. If the user has changed the RSS settings to use more queues then CPUS, we want to trust they know what they are doing and let them. More importantly, if we tell them that is what we did, we want to actually do it and allow traffic into all of the queues we have allocated. This does not change the default setting to initially allocate only the number of CPUS of queue pairs. Change-ID: Ie941a96e806e4bcd016addb4e17affb46770ada5 Signed-off-by:

The i40e_suspend() function was failing to save PCI state and this would result in a kernel stack trace from a WARN_ONCE in the pci_legacy_suspend() function. Add a call to pci_save_state() to fix that problem. Change-ID: I4736e62bb660966bd208cc8af617a14cb07fc4bd Signed-off-by:

The i40e_suspend() function calls another function that preps the device for the power save and resume by freeing all the Tx/Rx resources and interrupts but that function does not free the "other" causes interrupt vector and IRQ. It also fails to call synchronize_irq() before freeing the IRQ vectors. This sometimes may result in some AER errors on those systems with that PCIe error reporting feature enabled. Call synchronize_irq() before freeing IRQ vectors and explicitly free the other causes interrupt resources and shut down that MSIX interrupt.

If the user adds an obscene amount of MAC addresses, the driver will run into the situation where it has too many address requests to fit into a single PF message. The driver checks for this case, and calculates the maximum number of messages that it can send. Then it completely ignores this count and overflows the buffer. Fix this by checking the address count and bailing out of the loop at the appropriate time. Change-ID: If8dcbb04602c75941dc0cd8309065e1de9ca791c Signed-off-by:

There is no prevention of a concurrent call to both fixed_mdio_read() and fixed_phy_update_state(), which can result in the state being modified while it's being inspected. Fix this by using a seqcount to detect modifications, and memcpy()ing the state. We remain slightly naughty here, calling link_update() and updating the link status within the read-side loop - which would need rework of the design to change. Reviewed-by:

Generate software phy registers as and when requested, rather than duplicating the state in fixed_phy. This allows us to eliminate the duplicate storage of of the same data, which is only different in format. As fixed_phy_update_regs() no longer updates register state, rename it to fixed_phy_update().

In this mode the moderation timer will restart upon new completion (CQE) generation rather than upon interrupt generation. The outcome is that for bursty traffic the period timer will never expire and thus only the moderation frames counter will dictate interrupt generation, thus the interrupt rate will be relative to the incoming packets size. If the burst seizes for "moderation period" time then an interrupt will be issued immediately. CQE based moderation is off by default and can be controlled via ethtool set_priv_flags. Performance tested on ConnectX4-Lx 50G. Less packet loss in netperf UDP and TCP tests, with no bw degradation, for both single and multi streams, with message sizes of 64, 1024, 1472 and 32768 byte.

Configuring and managing HW rate limit tables. The HW holds a table of rate limits, each rate is associated with an index in that table. Later a Send Queue uses this index to set the rate limit. Multiple Send Queues can have the same rate limit, which is represented by a single entry in this table. Even though a rate can be shared, each queue is being rate limited independently of others. The SW shadow of this table holds the rate itself, the index in the HW table and the refcount (number of queues) working with this rate. The exported functions are mlx5_rl_add_rate and mlx5_rl_remove_rate. Number of different rates and their values are derived from HW capabilities. Signed-off-by:

Patch 2 adds support to configure asymmetric number of rx/tx queues via ethtool set-channels option.
