Struct XdpConfig

pub struct XdpConfig {
    pub zero_copy: Option<bool>,
    pub huge_page: Option<bool>,
    pub need_wakeup: Option<bool>,
}

Configuration options for creating an AF_XDP socket.

Fields

zero_copy: Option<bool>

Enables or disables zero-copy mode.

• Some(true): Enables XDP_ZEROCOPY.
• Some(false): Enables XDP_COPY.
• None: The kernel’s default behavior is used (typically copy mode).

huge_page: Option<bool>

Enables or disables huge pages for the UMEM.

• Some(true): Attempts to use huge pages.
• Some(false): Uses standard page sizes.
• None: The implementation default is used (typically standard pages).

need_wakeup: Option<bool>

Sets the XDP_USE_NEED_WAKEUP flag.

• Some(true): The flag is set. The application must call kick() to wake up the kernel.
• Some(false): The flag is not set. The kernel polls without needing a wakeup call.
• None: Defaults to true.
