Struct VirtqDesc 

#[repr(C)]
pub struct VirtqDesc {
    pub addr: u64,
    pub len: u32,
    pub flags: u16,
    pub next: u16,
}

Each descriptor points to a physically contiguous buffer in guest memory. Descriptors can be chained via the next field when VIRTQ_DESC_F_NEXT is set in flags.

Fields

addr: u64

Physical address of the guest buffer

len: u32

Length of the guest buffer in bytes

flags: u16

Descriptor flags (NEXT, WRITE, INDIRECT)

next: u16

Index of the next descriptor in the chain (valid if NEXT flag is set)
