@ -86,6 +86,20 @@ then the next program in the chain (A) will see those changes,
*not* the original input ``setsockopt`` arguments. The potentially
modified values will be then passed down to the kernel.
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
use the original buffer from the userspace. Any modifications
done by the BPF program to the ``optval`` are ignored.
* Set ``optlen`` to the value less than ``PAGE_SIZE``, which
indicates that the kernel should use BPF's trimmed ``optval``.
When the BPF program returns with the ``optlen`` greater than
``PAGE_SIZE``, the userspace will receive ``EFAULT`` errno.
Example

*
* Add new filter to Hardware Filter Block to match and direct Rx traffic to
* desired Rx queue.
*
* f_data is an array of unsigned 32-bit integers where each 32-bit integer
* provides filter data for 2 bytes (4 nibbles) of Rx frame:
*
* bits 31:20 - unused
* bit 19 - nibble 0 match enable
* bit 18 - nibble 1 match enable
* bit 17 - nibble 2 match enable
* bit 16 - nibble 3 match enable
* bits 15:12 - nibble 0 data
* bits 11:8 - nibble 1 data
* bits 7:4 - nibble 2 data
* bits 3:0 - nibble 3 data
*
* 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 0x00: 0x00000000, 0x00000000, 0x00000000, 0x00000000,
* Rx frame offset 0x08: 0x00000000, 0x00000000, 0x000F0800, 0x00084000,
* Rx frame offset 0x10: 0x00000000, 0x00000000, 0x00000000, 0x00030011,
* };
*
* To add the filter to HFB and direct the traffic to Rx queue 0, call:
* bcmgenet_hfb_add_filter(priv, hfb_filter_ipv4_udp,
* ARRAY_SIZE(hfb_filter_ipv4_udp), 0);
