Date: Sun, 23 Aug 2020 11:06:27 +0300 From: Ido Schimmel <idosch@...sch.org> To: netdev@...r.kernel.org Cc: davem@...emloft.net, kuba@...nel.org, jiri@...dia.com, mlxsw@...dia.com, Ido Schimmel <idosch@...lanox.com> Subject: [PATCH net-next 6/7] selftests: mlxsw: Reduce runtime of tc-police scale test From: Ido Schimmel <idosch@...lanox.com> Currently, the test takes about 626 seconds to complete because of an inefficient use of the device's TCAM. Reduce the runtime to 202 seconds by inserting all the flower filters with the same preference and mask, but with a different key. In particular, this reduces the deletion of the qdisc (which triggers the deletion of all the filters) from 66 seconds to 0.2 seconds. This prevents various netlink requests from user space applications (e.g., systemd-networkd) from timing-out because RTNL is not held for too long anymore.
