From f7ab7b2d9bc0f42c1e766d22d49dd0dc4f28abb6 Mon Sep 17 00:00:00 2001 From: Steven Luong Date: Thu, 13 Feb 2020 09:27:38 -0800 Subject: avf: Handle chain buffer in TX properly For chain buffer, need to traverse b->next_buffer to transmit all buffers in the chain. Only set EOP at the last descriptor in the chain to signal this is a chain descriptor. Introduce slow path to handle ring wrap. This is needed because chain buffer may consist of multiple pieces and it may span from near the end of the ring to the beginning of the ring.
