+Large optval
+============
+When the ``optval`` is greater than the ``PAGE_SIZE``, the BPF program
+can access only the first ``PAGE_SIZE`` of that data. So it has to options:
+
+* Set ``optlen`` to zero, which indicates that the kernel should

+When the BPF program returns with the ``optlen`` greater than
+``PAGE_SIZE``, the userspace will receive ``EFAULT`` errno.

- *
- * bits 31:20 - unused
- * bit 19 - nibble 0 match enable

- * Example:
- * In order to match:
- * - Ethernet frame type = 0x0800 (IP)
- * - IP version field = 4
- * - IP protocol field = 0x11 (UDP)
- *
- * The following filter is needed:
- * u32 hfb_filter_ipv4_udp[] = {

- * Rx frame offset 0x10: 0x00000000, 0x00000000, 0x00000000, 0x00030011,
- * };
- *
- * To add the filter to HFB and direct the traffic to Rx queue 0, call:
