2021-09-18wcn36xx: Ensure finish scan is not requested before start scanJoseph Gates2-1/+5
commit d195d7aac09bddabc2c8326fb02fcec2b0a2de02 upstream. If the operating channel is the first in the scan list, it was seen that a finish scan request would be sent before a start scan request was sent, causing the firmware to fail all future scans. Track the current channel being scanned to avoid requesting the scan finish before it starts.

2021-09-15ice: Only lock to update netdev dev_addrBrett Creeley1-4/+9
[ Upstream commit b357d9717be7f95fde2c6c4650b186a995b71e59 ] commit 3ba7f53f8bf1 ("ice: don't remove netdev->dev_addr from uc sync list") introduced calls to netif_addr_lock_bh() and netif_addr_unlock_bh() in the driver's ndo_set_mac() callback. This is fine since the driver is updated the netdev's dev_addr, but since this is a spinlock, the driver cannot sleep when the lock is held. Unfortunately the functions to add/delete MAC filters depend on a mutex. This was causing a trace with the lock debug kernel config options enabled when changing the mac address via iproute.

2021-09-15net/mlx5e: Block LRO if firmware asks for tunneled LROMaxim Mikityanskiy1-0/+15
[ Upstream commit 26ab7b384525ccfa678c518577f7f0d841209c8b ] This commit does a cleanup in LRO configuration. LRO is a parameter of an RQ, but its state is changed by modifying a TIR related to the RQ. The current status: LRO for tunneled packets is not supported in the driver, inner TIRs may enable LRO on creation, but LRO status of inner TIRs isn't changed in mlx5e_modify_tirs_lro(). This is inconsistent, but as long as the firmware doesn't declare support for tunneled LRO, it works, because the same RQs are shared between the inner and outer TIRs. This commit does two fixes: 1. If the firmware has the tunneled LRO capability, LRO is blocked altogether, because it's not possible to block it for inner TIRs only, when the same RQs are shared between inner and outer TIRs, and the driver won't be able to handle tunneled LRO traffic. 2. mlx5e_modify_tirs_lro() is patched to modify LRO state for all TIRs, including inner ones, because all TIRs related to an RQ should agree on their LRO state.

2021-09-15net/mlx5e: Prohibit inner indir TIRs in IPoIBMaxim Mikityanskiy3-27/+7
[ Upstream commit 9c43f3865c2a03be104f1c1d5e9129c2a2bdba88 ] TIR's rx_hash_field_selector_inner can be enabled only when tunneled_offload_en = 1. tunneled_offload_en is filled according to the tunneled_offload_en field in struct mlx5e_params, which is false in the IPoIB profile. On the other hand, the IPoIB profile passes inner_ttc = true to mlx5e_create_indirect_tirs, which potentially allows the latter function to attempt to create inner indirect TIRs without having tunneled_offload_en set. This commit prohibits this behavior by passing inner_ttc = false to mlx5e_create_indirect_tirs. The latter function won't attempt to create inner indirect TIRs. As inner indirect TIRs are not created in the IPoIB profile (this commit blocks it explicitly, and even before they would have failed to be created), the call to mlx5e_create_inner_ttc_table in mlx5i_create_flow_steering is a no-op and can be removed.

2021-08-26i40e: Fix ATR queue selectionArkadiusz Kubalewski1-2/+1
[ Upstream commit a222be597e316389f9f8c26033352c124ce93056 ] Without this patch, ATR does not work. Receive/transmit uses queue selection based on SW DCB hashing method. If traffic classes are not configured for PF, then use netdev_pick_tx function for selecting queue for packet transmission. Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx, which ensures that packet is transmitted/received from CPU that is running the application. Reproduction steps: 1. Load i40e driver 2. Map each MSI interrupt of i40e port for each CPU 3. Disable ntuple, enable ATR i.e.: ethtool -K $interface ntuple off ethtool --set-priv-flags $interface flow-director-atr 4. Run application that is generating traffic and is bound to a single CPU, i.e.: taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10 5. Observe behavior: Application's traffic should be restricted to the CPU provided in taskset.
