2018-08-01selftests: mlxsw: Add test for ip_forward_update_priorityPetr Machata1-0/+233
Verify that with that sysctl turned off, DSCP prioritization and rewrite works the same way as in qos_dscp_bridge test. However when the sysctl is charged, there should be a reprioritization after routing stage, which will be observed by a different DSCP rewrite on egress.

2018-08-01selftests: forwarding: Move DSCP capture to lib.shPetr Machata1-42/+0
dscp_capture_install() and dscp_capture_uninstall() are going to be useful for a test added by a following patch, move them therefore to lib.sh together with related helpers. While doing so, change the rule preference from mere DSCP value to DSCP+100 in order to support adding captures of packets with DSCP of 0.

2018-08-01selftests: forwarding: Move lldpad waiting to lib.shPetr Machata1-20/+3
The function lldpad_wait() will be useful for a test added by a following patch. Likewise would the "sleep 5" with its extensive comment. Therefore move lldpad_wait() to lib.sh in order to allow reuse. Rename it to lldpad_app_wait_set() to recognize that what this is intended to wait on are the pending APP sets. For the sleeping, add a function lldpad_app_wait_del(). That will serve to hold the related explanatory comment (which edit for clarity), and as a token in the caller to identify the sites where this sort of waiting takes place. That will serve when/if a better way to handle this business is found. Signed-off-by: Petr Machata <petrm@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.

2018-07-29selftests: mlxsw: qos_dscp_bridge: FixPetr Machata1-2/+2
There are two problems in this test case: - When indexing in bash associative array, the subscript is interpreted as string, not as a variable name to be expanded. - The keys stored to t0s and t1s are not DSCP values, but priority + base (i.e. the logical DSCP value, not the full bitfield value). In combination these two bugs conspire to make the test just work, except it doesn't really test anything and always passes. Fix the above two problems in obvious manner.

Add a test that exercises the new code. Send DSCP-tagged packets, and observe how they are prioritized in the switch and the DSCP is updated on egress again.
