24 syscall. Associated with each XSK are two rings: the RX ring and the
25 TX ring. A socket can receive packets on the RX ring and it can send
28 to have at least one of these rings for each socket. An RX or TX
30 UMEM. RX and TX can share the same UMEM so that a packet does not have
31 to be copied between RX and TX. Moreover, if a packet needs to be kept
44 to fill in with RX packet data. References to these frames will then
45 appear in the RX ring once each packet has been received. The
48 space, for either TX or RX. Thus, the frame addrs appearing in the
50 TX ring. In summary, the RX and FILL rings are used for the RX path
62 then receive frame addr references in its own RX ring that point to
65 process has to create its own socket with associated RX and TX rings,
123 There are a four different kind of rings: Fill, Completion, RX and
129 with the UMEM must have an RX queue, TX queue or both. Say, that there
130 is a setup with four sockets (all doing TX and RX). Then there will be
131 one Fill ring, one Completion ring, four TX rings and four RX rings.
154 Frames passed to the kernel are used for the ingress path (RX rings).
175 RX Ring
178 The RX ring is the receiving side of a socket. Each entry in the ring
183 descriptors will (or can) appear on the RX ring.
