* Merge branch 'mlxsw-Support-bridge-router-interfaces-with-non-default-VLAN'David S. Miller2018-06-265-14/+323
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: David S. Miller <davem@davemloft.net>
| * selftests: forwarding: Test routed bridge interfacePetr Machata2018-06-262-0/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | 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.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: David S. Miller <davem@davemloft.net>

|/ | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a sparse warning about using an incorrect type in argument 2 of ocelot_write_rix(), as an u32 was expected but a __be32 was given. The conversion to u32 is forced, which is safe as the value will be written as-is in the hardware without any modification.

| | * net: mvneta: fix the Rx desc DMA address in the Rx pathAntoine Tenart2018-06-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When using s/w buffer management, buffers are allocated and DMA mapped. When doing so on an arm64 platform, an offset correction is applied on the DMA address, before storing it in an Rx descriptor. The issue is this DMA address is then used later in the Rx path without removing the offset correction. Thus the DMA address is wrong, which can led to various issues. This patch fixes this by removing the offset correction from the DMA address retrieved from the Rx descriptor before using it in the Rx path.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After recieving MLD querys, we update idev->mc_maxdelay with max_delay from query header. This make the later unsolicited reports have the same interval with mc_maxdelay, which means we may send unsolicited reports with long interval time instead of default configured interval time. Also as we will not call ipv6_mc_reset() after device up. This issue will be there even after leave the group and join other groups.
