From d9114263d00dac608e87aa27761574202bd009c2 Mon Sep 17 00:00:00 2001 From: Vedang Patel Date: Thu, 18 Jul 2019 12:55:39 -0700 Subject: [PATCH] etf: Add skip_sock_check ETF Qdisc currently checks for a socket with SO_TXTIME socket option. If either is not present, the packet is dropped. In the future commits, we want other Qdiscs to add packet with launchtime to the ETF Qdisc. Also, there are some packets (e.g. ICMP packets) which may not have a socket associated with them. So, add an option to skip this check.
