selftests: mlxsw: Fix test failure on Spectrum-4

2023-08-19T02:41:06+00:00

Remove assumptions about shared buffer cell size and instead query the cell size from devlink. Adjust the test to send small packets that fit inside a single cell. Tested on Spectrum-{1,2,3,4}.

selftests: mlxsw: rtnetlink: Drop obsolete tests

2023-07-21T07:54:04+00:00

Support for enslaving ports to LAGs with uppers will be added in the following patches. Selftests to make sure it actually does the right thing are ready and will be sent as a follow-up. Similarly, ordering of MACVLAN creation and RIF creation will be relaxed and it will be permitted to create a MACVLAN first. Thus these two tests are obsolete. Drop them.

selftests: mlxsw: one_armed_router: Use port MAC for bridge address

2023-06-21T21:02:52+00:00

In a future patch, mlxsw will start adding RIFs to uppers of front panel port netdevices, if they have an IP address. At the time that the front panel port is enslaved to the bridge, the bridge MAC address does not have the same prefix as other interfaces in the system. On Nvidia Spectrum-1 machines all the RIFs have to have the same 38-bit MAC address prefix. Since the bridge does not obey this limitation, the RIF cannot be created, and the enslavement attempt is vetoed on the grounds of the configuration not being offloadable. The bridge eventually inherits MAC address from its first member, after the enslavement is acked. A number of (mainly VXLAN) selftests already work around the problem by setting the MAC address to whatever it will eventually be anyway. Do the same for this selftest.
