Hyper-V does not expose the normal Intel PF/VF mailbox. Import the Hyper-V operation overrides from DPDK and complete its reset callback with the configuration-space mechanism submitted by Microsoft. Route ixv operations through the operation table, use mailbox API 1.0, and limit this environment to one queue pair. Claim the 82599, X540, X550, X550EM-X, and X550EM-A Hyper-V device IDs listed by DPDK. Select the same path for the E610 Hyper-V subdevice identity defined there. For E610/Linkville, read the emulated VFLINKS-format status from PCI configuration space at offset 0x209. Older families retain the MMIO VFLINKS path. Treat receive-mode changes as host-owned no-ops and do not retry VLAN operations that Hyper-V permanently rejects. Limit the Hyper-V 82599 MTU to 1504 because its VF does not implement the X540 RLPML field. Use mailbox reset indications only to refresh cached Hyper-V link state. Hyper-V does not provide the mailbox handshake required to treat that indication as a request for an iflib reinitialization. Tested on 82599 and E610 (with a followup commit) with Windows Server 2025 Hyper-V.

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.
