| 2020-11-24 | igbvf: Refactor traces | Karen Sornek | |
| Refactoring "PF still resetting" and changing "Failed to add vlan id" to "Vlan id is not added" messages because previous version looked like a bug - it informed about changes that worked as designed but might confuse users Signed-off-by: Karen Sornek <karen.sornek@intel.com> Reviewed-by: Aleksandr Loktionov <aleksandr.loktionov@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com> | |||
| 2020-09-25 | intel-ethernet: clean up W=1 warnings in kdoc | Jesse Brandeburg | |
| This takes care of all of the trivial W=1 fixes in the Intel Ethernet drivers, which allows developers and maintainers to build more of the networking tree with more complete warning checks. There are three classes of kdoc warnings fixed: - cannot understand function prototype: 'x' - Excess function parameter 'x' description in 'y' - Function parameter or member 'x' not described in 'y' All of the changes were trivial comment updates on function headers. Inspired by Lee Jones' series of wireless work to do the same. Compile tested only, and passes simple test of $ git ls-files *.[ch] | egrep drivers/net/ethernet/intel | \ xargs scripts/kernel-doc -none Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

| 2020-07-30 | igbvf: use generic power management | Vaibhav Gupta | |
| Remove legacy PM callbacks and use generic operations. With legacy code, drivers were responsible for handling PCI PM operations like pci_save_state(). In generic code, all these are handled by PCI core. The generic suspend() and resume() are called at the same point the legacy ones were called. Thus, it does not affect the normal functioning of the driver. __maybe_unused attribute is used with .resume() but not with .suspend(), as .suspend() is called by .shutdown(). Compile-tested only.

| 2020-06-25 | net/intel: remove driver versions from Intel drivers | Jeff 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 allows incrementing the correct timeout statistic without any mess. Down the road, devices can learn to reset just the specific queue.

| 2019-04-08 | drivers: Remove explicit invocations of mmiowb() | Will Deacon | |
| mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

| 2018-11-21 | ethernet/intel: consolidate NAPI and NAPI exit | Jesse Brandeburg | |
| While reviewing code, I noticed that Eric Dumazet recommends that drivers check the return code of napi_complete_done, and use that to decide to enable interrupts or not when exiting poll. One of the Intel drivers was already fixed (ixgbe). Upon looking at the Intel drivers as a whole, we are handling our polling and NAPI exit in a few different ways based on whether we have multiqueue and whether we have Tx cleanup included. Several drivers had the bug of exiting NAPI with return 0, which appears to mess up the accounting in the stack. Consolidate all the NAPI routines to do best known way of exiting and to just mostly look like each other. 1) check return code of napi_complete_done to control interrupt enable 2) return the actual amount of work done. 3) return budget immediately if need NAPI poll again Tested the changes on e1000e with a high interrupt rate set, and it shows about an 8% reduction in the CPU utilization when busy polling because we aren't re-enabling interrupts when we're about to be polled.

It also overlapped with Jiri's change to guard the rhashtable_remove_fast() call with a check against tc_skip_sw(). 5) In mlx4, a revert bug fix in 'net' overlapped with some unrelated changes in 'net-next'. 6) In geneve, a stale header pointer after pskb_expand_head() bug fix in 'net' overlapped with a large reorganization of the same code in 'net-next'. Since the 'net-next' code no longer had the bug in question, there was nothing to do other than to simply take the 'net-next' hunks. Signed-off-by: David S. Miller <davem@davemloft.net> | |||

| A similar issue was addressed a few years ago in the following thread: http://www.spinics.net/lists/netdev/msg245877.html At that time there were concerns that removing this statement may cause other side effects. However the submitter addressed those concerns. But the dialogue went cold. We have a new case where a customers application is registering and un-registering multicast addresses every few seconds. This is leading to many "Link is Up" messages in the logs as a result of the "netif_carrier_off(netdev)" statement called by igbvf_msix_other(). Also on some kernels it is interfering with the bonding driver causing it to failover and subsequently affecting connectivity. The Sourgeforge driver does not make this call and is therefore not affected. If there were any side effects I would expect that driver to also be affected. I have tested re-loading the igbvf driver and downing the adapter with the PF entity on the host where the VM has this patch. When I bring it back up again connectivity is restored as expected. Therefore I request that this patch gets submitted.

| 2016-02-24 | igbvf: Add support for generic Tx checksums | Alexander Duyck | |
| This patch adds support for generic Tx checksums to the igbvf driver. It turns out this is actually pretty easy after going over the datasheet as we were doing a number of steps we didn't need to. In order to perform a Tx checksum for an L4 header we need to fill in the following fields in the Tx descriptor: MACLEN (maximum of 127), retrieved from: skb_network_offset() IPLEN (maximum of 511), retrieved from: skb_checksum_start_offset() - skb_network_offset() TUCMD.L4T indicates offset and if checksum or crc32c, based on: skb->csum_offset The added advantage to doing this is that we can support inner checksum offloads for tunnels and MPLS while still being able to transparently insert VLAN tags. I also took the opportunity to clean-up many of the feature flag configuration bits to make them a bit more consistent between drivers. In the case of the VF drivers this meant adding support for SCTP CRCs, and inner checksum offloads for MPLS and various tunnel types.

| 2015-10-16 | drivers/net: get rid of unnecessary initializations in .get_drvinfo() | Ivan Vecera | |
| Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len, eedump_len & regdump_len fields in their .get_drvinfo() ethtool op. It's not necessary as these fields is filled in ethtool_get_drvinfo(). v2: removed unused variable v3: removed another unused variable Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

| 2015-09-22 | igbvf: Enable TSO for stacked VLAN | Toshiaki Makita | |
| Setting ndo_features_check to passthru_features_check allows the driver to skip the check for multiple tagged TSO packets and enables stacked VLAN TSO. Tested with I350.

| 2015-08-18 | igbvf: clear buffer_info->dma after dma_unmap_single() | Stefan Assmann | |
| The driver doesn't clear buffer_info->dma after calling dma_unmap_single() in all cases. This has been discovered by changing the mtu twice, which caused the following backtrace.
