Enum OutgoingPacketType

pub enum OutgoingPacketType<'a> {
    InBandNoCompletion,
    InBandWithCompletion,
    Completion,
    GpaDirect(&'a [PagedRange<'a>]),
    TransferPages(u16, &'a [TransferPageRange]),
}

The outgoing packet type variants.

Variants

InBandNoCompletion

A non-transactional data packet.

InBandWithCompletion

A transactional data packet.

Completion

A completion packet.

GpaDirect(&'a [PagedRange<'a>])

A GPA direct packet, which can reference memory outside the ring by address.

Not supported on the host side of the ring.

TransferPages(u16, &'a [TransferPageRange])

A transfer page packet, which can reference memory outside the ring by a buffer ID and a set of offsets into some pre-established buffer (typically a GPADL).

Used by networking. Should not be used in new devices–just embed the buffer offsets in the device-specific packet payload.
