/* Some Ocelot switches are integrated into the SoC without the |
|
* extraction IRQ line connected to the ARM GIC. By enabling this |
|
* workaround, the few packets that are delivered to the CPU port |
|
* module (currently only PTP) are copied not only to the hardware CPU |
|
* port module, but also to the 802.1Q Ethernet CPU port, and polling |
|
* the extraction registers is triggered once the DSA tagger sees a PTP |
|
* frame. The Ethernet frame is only used as a notification: it is |
|
* dropped, and the original frame is extracted over MMIO and annotated |
|
* with the RX timestamp. |
