2022-01-27net/mlx5e: Pass attr arg for attaching/detaching encapsRoi Dayan3-13/+20
In later commit that we will have multiple attr instances per flow we would like to pass a specific attr instance to set encaps. Currently the mlx5_flow object contains a single mlx5_attr instance. However, multi table actions (e.g. CT) instantiate multiple attr instances. Currently mlx5e_attach/detach_encap() reads the first attr instance from the flow instance. Modify the functions to receive the attr instance as a parameter which is set by the calling function.

2022-01-27ice: xsk: Borrow xdp_tx_active logic from i40eMaciej Fijalkowski3-3/+14
One of the things that commit 5574ff7b7b3d ("i40e: optimize AF_XDP Tx completion path") introduced was the @xdp_tx_active field. Its usage from i40e can be adjusted to ice driver and give us positive performance results. If the descriptor that @next_dd points to has been sent by HW (its DD bit is set), then we are sure that at least quarter of the ring is ready to be cleaned. If @xdp_tx_active is 0 which means that related xdp_ring is not used for XDP_{TX, REDIRECT} workloads, then we know how many XSK entries should placed to completion queue, IOW walking through the ring can be skipped.

Apply the logic that was done for regular XDP from commit 9610bd988df9 ("ice: optimize XDP_TX workloads") to the ZC side of the driver. On top of that, introduce batching to Tx that is inspired by i40e's implementation with adjustments to the cleaning logic - take into the account NAPI budget in ice_clean_xdp_irq_zc().

2022-01-27ice: xsk: Avoid potential dead AF_XDP Tx processingMaciej Fijalkowski1-0/+2
Commit 9610bd988df9 ("ice: optimize XDP_TX workloads") introduced @next_dd and @next_rs to ice_tx_ring struct. Currently, their state is not restored in ice_clean_tx_ring(), which was not causing any troubles as the XDP rings are gone after we're done with XDP prog on interface. For upcoming usage of mentioned fields in AF_XDP, this might expose us to a potential dead Tx side. Scenario would look like following (based on xdpsock): - two xdpsock instances are spawned in Tx mode - one of them is killed - XDP prog is kept on interface due to the other xdpsock still running * this means that XDP rings stayed in place - xdpsock is launched again on same queue id that was terminated on - @next_dd and @next_rs setting is bogus, therefore transmit side is broken To protect us from the above, restore the initial @next_rs and @next_dd values when cleaning the Tx ring.

Move desc_array from the driver to the pool. The reason behind this is that we can then reuse this array as a temporary storage for descriptors in all zero-copy drivers that use the batched interface. This will make it easier to add batching to more drivers. i40e is the only driver that has a batched Tx zero-copy implementation, so no need to touch any other driver.

2022-01-27ice: Make Tx threshold dependent on ring lengthMaciej Fijalkowski4-9/+12
XDP_TX workloads use a concept of Tx threshold that indicates the interval of setting RS bit on descriptors which in turn tells the HW to generate an interrupt to signal the completion of Tx on HW side. It is currently based on a constant value of 32 which might not work out well for various sizes of ring combined with for example batch size that can be set via SO_BUSY_POLL_BUDGET. Internal tests based on AF_XDP showed that most convenient setup of mentioned threshold is when it is equal to quarter of a ring length. Make use of recently introduced ICE_RING_QUARTER macro and use this value as a substitute for ICE_TX_THRESH. Align also ethtool -G callback so that next_dd/next_rs fields are up to date in terms of the ring size.

2022-01-27ice: xsk: Handle SW XDP ring wrap and bump tail more oftenMaciej Fijalkowski2-20/+81
Currently, if ice_clean_rx_irq_zc() processed the whole ring and next_to_use != 0, then ice_alloc_rx_buf_zc() would not refill the whole ring even if the XSK buffer pool would have enough free entries (either from fill ring or the internal recycle mechanism) - it is because ring wrap is not handled. Improve the logic in ice_alloc_rx_buf_zc() to address the problem above. Do not clamp the count of buffers that is passed to xsk_buff_alloc_batch() in case when next_to_use + buffer count >= rx_ring->count, but rather split it and have two calls to the mentioned function - one for the part up until the wrap and one for the part after the wrap.

2022-01-27ice: xsk: Force rings to be sized to power of 2Maciej Fijalkowski1-0/+8
With the upcoming introduction of batching to XSK data path, performance wise it will be the best to have the ring descriptor count to be aligned to power of 2. Check if ring sizes that user is going to attach the XSK socket fulfill the condition above. For Tx side, although check is being done against the Tx queue and in the end the socket will be attached to the XDP queue, it is fine since XDP queues get the ring->count setting from Tx queues.

2022-01-27net: phy: at803x: move page selection fix to config_initRobert Hancock1-24/+16
The fix to select the copper page on AR8031 was being done in the probe function rather than config_init, so it would not be redone after resume from suspend. Move this to config_init so it is always redone when needed.

2022-01-27net: ieee802154: at86rf230: Stop leaking skb'sMiquel Raynal1-2/+11
Upon error the ieee802154_xmit_complete() helper is not called. Only ieee802154_wake_queue() is called manually. In the Tx case we then leak the skb structure. Free the skb structure upon error before returning when appropriate. As the 'is_tx = 0' cannot be moved in the complete handler because of a possible race between the delay in switching to STATE_RX_AACK_ON and a new interrupt, we introduce an intermediate 'was_tx' boolean just for this purpose. There is no Fixes tag applying here, many changes have been made on this area and the issue kind of always existed.

2022-01-27net: ieee802154: hwsim: Ensure proper channel selection at probe timeMiquel Raynal1-0/+1
Drivers are expected to set the PHY current_channel and current_page according to their default state. The hwsim driver is advertising being configured on channel 13 by default but that is not reflected in its own internal pib structure. In order to ensure that this driver consider the current channel as being 13 internally, we at least need to set the pib->channel field to 13.

GFP_KERNEL will allow blocking which allows it to succeed more often in a low memory enviornment but in the hotpath we do not want to allow the allocation to block.
