Add the reoffload tcf_proto_op in matchall to generate an offload message for each filter in the given tcf_proto. Call the specified callback with this new offload message. The function only returns an error if the callback rejects adding a 'hardware only' rule. Ensure matchall flags correctly report if the rule is in hw by keeping a reference counter for the number of instances of the rule offloaded. Only update the flag when this counter changes from or to 0. Signed-off-by:

Add the reoffload tcf_proto_op in flower to generate an offload message for each filter in the given tcf_proto. Call the specified callback with this new offload message. The function only returns an error if the callback rejects adding a 'hardware only' rule. A filter contains a flag to indicate if it is in hardware or not. To ensure the reoffload function properly maintains this flag, keep a reference counter for the number of instances of the filter that are in hardware. Only update the flag when this counter changes from or to 0. Add a generic helper function to implement this behaviour. Signed-off-by:

Create a new tcf_proto_op called 'reoffload' that generates a new offload message for each node in a tcf_proto. Pointers to the tcf_proto and whether the offload request is to add or delete the node are included. Also included is a callback function to send the offload message to and the option of priv data to go with the cb. Signed-off-by:

The *enum* RPADIR_BIT was declared in the commit 86a74ff2 ("net: sh_eth: add support for Renesas SuperH Ethernet") adding SH771x support, however the SH771x manual doesn't have the RPADIR register described and, moreover, tells why the padding insertion must not be used. The newer SoC manuals do have RPADIR documented, though with somewhat different layout -- update the *enum* according to these manuals... Signed-off-by:

So far unsupported WoL options are silently ignored. Change this and reject attempts to set unsupported options. This prevents situations where a user tries to set an unsupported WoL option and is under the impression it was successful because ethtool doesn't complain. Signed-off-by:

Commit 5691484d ("net: ip6_gre: Fix headroom request in ip6erspan_tunnel_xmit()") and commit 01b8d064 ("net: ip6_gre: Request headroom in __gre6_xmit()") fix problems in reserving headroom in the packets tunneled through ip6gre/tap and ip6erspan netdevices. These two patches included snippets that reproduced the issues. This patch elevates the snippets to a full-fledged test case. Suggested-by:

Ido Schimmel says: ==================== mlxsw: Support bridge router interfaces with non-default VLAN Petr says: When traffic is inserted on a router interface associated with an 802.1q bridge, the VLAN that the traffic appears on is determined by PVID of the bridge device itself. However currently mlxsw always configures such traffic to be forwarded to VLAN 1, regardless of the bridge PVID. Fix the problem by modifying the FID-handling code to assign such traffic not to FID that corresponds to VLAN 1, but to a FID that corresponds to the configured PVID. Bail out if there is no PVID. This is implemented in patches #1 and #2. From that point on, also forbid any changes to bridge device PVID, because such changes would not be reflected. This is implemented in patches #3, #4 and #5. Finally in patch #6, introduce tests that use bridge as a routed interface, and test mlxsw in both the currently-supported scenario of using PVID 1, and the newly-supported one of using a custom PVID. ==================== Signed-off-by: -
Petr Machata authored
Add test for cases where bridge itself acts as a router interface, with front panel port attached to the bridge in question. In the first test (router_bridge.sh), VLAN memberships are not configured in any way, and everything uses default PVID of 1. Thus traffic in $h1 and $h2 is untagged. This test ensures that the previous patches didn't break a currently working scenario. In the second test (router_bridge_vlan.sh), a VLAN 555 pvid untagged is added to the bridge CPU port, with that VLAN leaving the bridge tagged through its sole member port. The traffic is therefore expected to come out tagged at $h1. This tests the fix introduced in the previous patches. Signed-off-by:

When traffic passes through a router port, it needs to be assigned a FID for ASIC to forward correctly. For bridges, this FID used to be the one corresponding to VLAN 1. In a previous patch, this was changed to instead use the PVID at the time that the RIF is created. This patch guards PVID changes after the RIF was introduced. Signed-off-by:

Convert GRO receive over to hash table. When many parallel flows are present and being received on the same RX queue, GRO processing can become expensive because each incoming frame must traverse the per-NAPI GRO list at each protocol layer of GRO receive (eth --> ipv{4,6} --> tcp). Use the already computed hash to chain these SKBs in a hash table instead of a simple list. The first patch makes the GRO list a true list_head. The second patch implements the hash table. This series patches basic testing and I added some diagnostics to make sure we really were aggregating GRO frames :-) Signed-off-by: -

Manage pending per-NAPI GRO packets via list_head. Return an SKB pointer from the GRO receive handlers. When GRO receive handlers return non-NULL, it means that this SKB needs to be completed at this time and removed from the NAPI queue. Several operations are greatly simplified by this transformation, especially timing out the oldest SKB in the list when gro_count exceeds MAX_GRO_SKBS, and napi_gro_flush() which walks the queue in reverse order.
