We can install forwarding packets rule between uplink in switchdev mode, as show below. But the hardware does not do that as expected (mlnx_perf -i $PF1, we can't get the counter of the PF1). By the way, if we add the uplink PF0, PF1 to Open vSwitch and enable hw-offload, the rules can be offloaded but not work fine too. This patch add a check and if so return -EOPNOTSUPP. $ tc filter add dev $PF0 protocol all parent ffff: prio 1 handle 1 \ flower skip_sw action mirred egress redirect dev $PF1 $ tc -d -s filter show dev $PF0 ingress skip_sw in_hw in_hw_count 1 action order 1: mirred (Egress Redirect to device enp130s0f1) stolen ...

The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

Russell King says: ==================== rework phylink interface for split MAC/PCS support The following series changes the phylink interface to allow us to better support split MAC / MAC PCS setups. The fundamental change required for this turns out to be quite simple. Today, mac_config() is used for everything to do with setting the parameters for the MAC, and mac_link_up() is used to inform the MAC driver that the link is now up (and so to allow packet flow.) mac_config() also has had a few implementation issues, with folk who believe that members such as "speed" and "duplex" are always valid, where "link" gets used inappropriately, etc. With the proposed patches, all this changes subtly - but in a backwards compatible way at this stage. We pass the the full resolved link state (speed, duplex, pause) to mac_link_up(), and it is now guaranteed that these parameters to this function will always be valid (no more SPEED_UNKNOWN or DUPLEX_UNKNOWN here - unless phylink is fed with such things.) Drivers should convert over to using the state in mac_link_up() rather than configuring the speed, duplex and pause in the mac_config() method. The patch series includes a number of MAC drivers which I've thought have been easy targets - I've left the remainder as I think they need maintainer input. However, *all* drivers will need conversion for future phylink development. v2: add ocelot/felix and qca/ar9331 DSA drivers to patch 2, add received tested-by so far. ==================== Signed-off-by: -

Propagate the resolved link parameters via the mac_link_up() call for MACs that do not automatically track their PCS state. We propagate the link parameters via function arguments so that inappropriate members of struct phylink_link_state can't be accessed, and creating a new structure just for this adds needless complexity to the API.

Currently, the test inserts X /32 routes and for each route it is testing that a packet sent from the first host is received by the second host, which is very time-consuming. Instead only validate the offload flag of each route and get the same result. Wait between the creation of the routes and the offload validation in order to make sure that all the routes were successfully offloaded. Signed-off-by:

The test checks that packets are trapped when they should egress a router interface (RIF) that has become disabled. This is a temporary state in a RIF's deletion sequence. Currently, the test deletes the RIF by flushing all the IP addresses configured on the associated netdev (br0). However, this is racy, as this also flushes all the routes pointing to the netdev and if the routes are deleted from the device before the RIF is disabled, then no packets will try to egress the disabled RIF and the trap will not be triggered. Instead, trigger the deletion of the RIF by unlinking the mlxsw port from the bridge that is backing the RIF. Unlike before, this will not cause the kernel to delete the routes pointing to the bridge. Note that due to current mlxsw locking scheme the RIF is always deleted first, but this is going to change.
