From b9b6b68e8abd101be6eb5330e4999218c696d1e8 Mon Sep 17 00:00:00 2001 From: Björn Töpel Date: Wed, 2 May 2018 13:01:25 +0200 Subject: xsk: add Rx queue setup and mmap support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Another setsockopt (XDP_RX_QUEUE) is added to let the process allocate a queue, where the kernel can pass completed Rx frames from the kernel to user process. The mmapping of the queue is done using the XDP_PGOFF_RX_QUEUE offset.
