The Windows PF can disable a VF transmit queue while continuing to report carrier up. Link polling alone then leaves the VF operationally up even though it cannot transmit. The reproduced VLAN failure shows this state with PF driver 14.1.5.0 and an MDD indication in the host trace. Check queue zero from the admin path only while the Hyper-V VF is running with sanitized queues and a completed host handshake. Report operational link down and invalidate the statistics baseline when the queue is disabled. Request recovery through the normal iflib stop/init path only when a fresh, accessible STATUS read reports carrier up. Rate limit requests if the host continues to hold the queue disabled, and leave recovery pending while carrier is down. Document the recovery behavior and clarify why the Hyper-V reset retains the VF-local software reset before its host reset/MAC exchange. Sponsored by: BBOX.io
FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
