2018-12-17bnxt_en: query force speeds before disabling autoneg mode.Vasundhara Volam
With autoneg enabled, PHY loopback test fails. To disable autoneg, driver needs to send a valid forced speed to FW. FW is not sending async event for invalid speeds. To fix this, query forced speeds and send the correct speed when disabling autoneg mode.

2018-12-17bnxt_en: Do not free port statistics buffer when device is down.Michael Chan
Port statistics which include RDMA counters are useful even when the netdevice is down. Do not free the port statistics DMA buffers when the netdevice is down. This is keep the snapshot of the port statistics and counters will just continue counting when the netdevice goes back up. Split the bnxt_free_stats() function into 2 functions. The port statistics buffers will only be freed when the netdevice is removed. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-12-17bnxt_en: Save ring statistics before reset.Michael Chan
With the current driver, the statistics reported by .ndo_get_stats64() are reset when the device goes down. Store a snapshot of the rtnl_link_stats64 before shutdown. This snapshot is added to the current counters in .ndo_get_stats64() so that the counters will not get reset when the device is down.

2018-12-17bnxt_en: Disable MSIX before re-reserving NQs/CMPL rings.Michael Chan
When bringing up a device, the code checks to see if the number of MSIX has changed. pci_disable_msix() should be called first before changing the number of reserved NQs/CMPL rings. This ensures that the MSIX vectors associated with the NQs/CMPL rings are still properly mapped when pci_disable_msix() masks the vectors. This patch will prevent errors when RDMA support is added for the new 57500 chips. When the RDMA driver shuts down, the number of NQs is decreased and we must use the new sequence to prevent MSIX errors.

2018-12-17bnxt_en: Reserve 1 stat_ctx for RDMA driver.Vasundhara Volam
bnxt_en requires same number of stat_ctxs as CP rings but RDMA requires only 1 stat_ctx. Also add a new parameter resv_stat_ctxs to better keep track of stat_ctxs reserved including resources used by RDMA. Add a stat_ctxs parameter to all the relevant resource reservation functions so we can reserve the correct number of stat_ctxs. Prior to this patch, we were not reserving the extra stat_ctx for RDMA and RDMA would not work on the new 57500 chips.

Calling bnxt_set_max_func_stat_ctxs() to modify max stat_ctxs requested or freed by the RDMA driver is wrong.

2018-12-17bnxt_en: Store the maximum NQs available on the PF.Michael Chan
The PF has a pool of NQs and MSIX vectors assigned to it based on NVRAM configurations. The number of usable MSIX vectors on the PF is the minimum of the NQs and MSIX vectors. Any excess NQs without associated MSIX may be used for the VFs, so we need to store this max_nqs value. max_nqs minus the NQs used by the PF will be the available NQs for the VFs.

2018-12-17net/mlx5e: Uninstantiate esw manager vport netdev on switchdev modeOr Gerlitz
Now, when we have a dedicated uplink representor, the netdev instance set over the esw manager vport (PF) is of no-use. As such, remove it once we're on switchdev mode and get it back to life when off switchdev. This is done by reloading the Ethernet interface as well (we already do that for the IB interface) from the eswitch code while going in/out of switchdev mode. The Eth add/remove entries are modified to act differently when called in switchdev mode. In this case we only deal with registration of the eth vport representors.

2018-12-17net/mlx5e: Use dedicated uplink vport netdev representorOr Gerlitz
Currently, when running in sriov switchdev mode, we are using the PF netdevice as the uplink representor, this is problematic from few aspects: - will break when the PF isn't eswitch manager (e.g smart NIC env) - misalignment with other NIC switchdev drivers - makes us have and maintain special code, hurts the driver quality/robustness - which in turn opens the door for future bugs As of each and all of the above, we move to have a dedicated netdev representor for the uplink vport in a similar manner done for for the VF vports. This includes the following: 1. have an uplink rep netdev as we have for VF reps 2. all reps use same load/unload functions 3. HW stats for uplink based on physical port counters and not vport counters 4. link state for the uplink managed through PAOS and not vport state 5. the uplink rep has sysfs link to the PF PCI function && uses the PF MAC address Signed-off-by: Or Gerlitz <ogerlitz@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

2018-12-16mlxsw: spectrum_acl: Set master RP index on transition to eRPNir Dotan
Bloom filter is updated on transitions from a single rule pattern, also called master RP, to eRP table and vice versa. Since rules are being written to or deleted from the Bloom filter on such transitions, it is not required to keep the same eRP bank ID for the master RP. Change master RP index assignment so it will be assigned with zero. This is consistent with the assignment of the first available spot that is used for allocating eRP's indices.

Bloom filter update is required only for rules which reside on an eRP. When the region has only a single rule pattern then eRP table is not used, however insertion of another pattern would trigger a move to an active eRP table so it is imperative to update the Bloom filter with all previously configured rules. Add a method that updates Bloom filter entries for all rules currently configured in the region, on the event of a transition from master mask to eRP, or vice versa. For that purpose, maintain a list of all A-TCAM rules within mlxsw_sp_acl_atcam_region.

2018-12-16mlxsw: spectrum_acl: Add Bloom filter handlingNir Dotan
Spectrum-2 HW uses Bloom filter in order to skip lookups on specific eRPs. It uses crc-16-Msbit-first calculation over a specific layout of a rule's key fields combined with eRP ID as well as region ID. Per potential lookup, iff the Bloom filter entry of the calculated index is empty, then the lookup can be skipped. Hence, the mlxsw driver should update the Bloom filter entry per each rule insertion or deletion when rules are part of an eRP. Add functions for adding and deleting entries in the Bloom filter. In order to do so also add crc-16 computation based on the specific Spectrum-2 polynomial and a function for encoding the crc-16 input in the manner dictated by HW implementation.

2018-12-15net: socionext: correctly recover txq after being fullIlias Apalodimas
Running pktgen with packets sizes > 512b ends up in the interface Txq getting stuck. "netsec 522d0000.ethernet eth0: netsec_netdev_start_xmit: TxQFull!" appears on dmesg but the interface never recovers. It requires an ifconfig down/up to make the interface usable again. The reason that triggers this, is a race condition between .ndo_start_xmit and the napi completion. The available budget is calculated first and indicates the queue is full. Due to a costly netif_err() the queue is not stopped in time while the napi completion runs, clears the irq and frees up descriptors, thus the queue never wakes up again. Fix this by moving the print after stopping the queue, make the print ratelimited, add barriers and check for cleaned descriptors..
