get rid of atomic_foo ops in the tx start and completion paths. atomics were used to coordinate updates to the number of available slots on the tx ring. start would use what was available, and txeof (completion) would add back freed slots. start and completion update a producer and consumer index respectively, so we can use those with the size of the ring to calculate space instead. while here i simplified what txeof does a fair bit, which combined with the removal of the atomics gives us a bit of a speed improvement. hrvoje popovski reports up to a 20% improvement in one environment, but 5 to 10 is probably more realistic. ive had this in a tree since 2017, but mpi's "Faster vlan(4) forwarding?" post made me dig it out and clean it up. ok jmatthew@ |

Transfers that span multiple TRBs which wrap around the ring and thus have the Link TRB inbetween must have the Chain Bit set in the Link TRB. Otherwise xHCI controllers might think that the transfer ends at that point. Fixes an issue that was most prominently seen as Invalid CSW error when using umass0 on octeon and i.MX8M.

Rework iwm(4) Tx rate selection. Ask firmware to retry at a constant Tx rate instead of successively lower rates. This provides better feedback to Tx rate scaling algorithms in our kernel and thus increases Tx throughput, especially on clean channels. Make the driver fall back to CCK rates on 2 GHz channels if 11n MCS don't work. Previously, we were relying on firmware to do this for us. Tested on 7260, 7265, 8260, 8265 by me, jcs@, tb@, solene@, Matthias Schmidt. |

Fix memory barrier in __mtx_leave(). membar_exit_before_atomic() cannot be used in the routine because there is no subsequent atomic operation. membar_exit() has to be used instead. The mistake has not caused problems because on most platforms membar_exit_before_atomic() is membar_exit(). Only amd64 and i386 have a dedicated membar_exit_before_atomic(), and their exit barriers are no-ops. OK dlg@ |

don't check the pseudowire type in tx and rx paths. whether the mpw interface is advertising "ethernet" or "ethernet- tagged" is something the ends of the wire agree on (ie, ldpd is configured a certain way), it is not something that affects ethernet encap or decap. the MPW ioctls can still configure it and read it, but it has no bearing on how the driver operates on packets. |

Re-enable interrupts on resume with RF switch disabled When disabling the switch, suspending and eventually resuming again with wifi still off, re-enabling the switch has no effect due to interrupts being disabled completely. To ensure seemless operation, explicitly enable interrupts during hardware initialization iff the switch is disabled. While here, initialize the interrupt mask up front to avoid clearing the previously set mask in any case. OK mlarkin, Feedback and OK ststp |

Introduce safe memory reclamation, a mechanism for reclaiming shared objects that readers can access without locking. This provides a basis for read-copy-update operations. Readers access SMR-protected shared objects inside SMR read-side critical section where sleeping is not allowed. To reclaim an SMR-protected object, the writer has to ensure mutual exclusion of other writers, remove the object's shared reference and wait until read-side references cannot exist any longer. As an alternative to waiting, the writer can schedule a callback that gets invoked when reclamation is safe. The mechanism relies on CPU quiescent states to determine when an SMR-protected object is ready for reclamation. The singly- and doubly-linked lists that can be used together with SMR. These lists allow lockless read access with a concurrent writer. Discussed with many OK mpi@ sashan@ |

Make xhci_ring_produce() check the previous TRB to find out if it needs the Chain Bit set or not instead of using the last parameter, which is used to mark the last TRB in a USB transfer, not in a TD. To make that work we need to setup the recently acquired TRB before calling xhci_xfer_get_trb() the next time. Thus setting up the initial TRB has to happen right away. To kick the transfer off we simply flip the toggle bit on the first TRB right at the end. Fixes regression for jcs@, dhill@ and stsp@ Initially discussed with mpi@ ok stsp@ |

Back in 2016 we enabled RTS threshold by default because it apparently helped us on a loaded hackathon wifi network. In 11n mode we are now using a heuristic for this. Disable RTS threshold for all other modes again because it can do more harm than good in many situations. This change may increase Tx throughput in 11a/g modes, though results depend on the driver. Some drivers, e.g. urtwn(4), keep using RTS regardless for unknown reasons and may need to be fixed separately. And we will keep using RTS if the AP enables 11g protection while 11b clients are around. |
