When offloading action trap on a qevent, pass to_dev of NULL to the SPAN module to trigger the mirror to the CPU port. Query the buffer drops policer and use it for policing of the trapped traffic. Signed-off-by:

As previously explained, packets that are dropped due to buffer related reasons (e.g., tail drop, early drop) can be mirrored to the CPU port. These packets are then trapped with one of the "mirror session" traps and their CQE includes the reason for which the packet was mirrored. Register with devlink a new trap, early_drop, and initialize the corresponding Rx listener with the appropriate mirror reason. Return an error in case user tries to change the traps' action, as this is not supported. Since Spectrum-1 does not support these traps, the above is only done for Spectrum-2 onwards. Signed-off-by:

Subsequent patches will need to register different traps for Spectrum-1 and Spectrum-2 onwards. Enable that by invoking a per-ASIC operation during traps initialization. Reviewed-by:

When unsetting policer base, the SPAN code currently uses refcount_dec(). However that function splats when the counter reaches zero, because reaching zero without actually testing is in general indicative of a missing cleanup. There is no cleanup to be done here, but nonetheless, use refcount_dec_and_test() as required. Signed-off-by:

With the latest net-next tree, if test suspend/resume after enabling WOL, we get error as below: [ 487.086365] dpm_run_callback(): mdio_bus_suspend+0x0/0x30 returns -16 [ 487.086375] PM: Device stmmac-0:00 failed to suspend: error -16 -16 means -EBUSY, this is because I didn't enable wakeup of the correct device when implementing phy based WOL feature. To be honest, I caught the issue when implementing phy based WOL and then fix it locally, but forgot to amend the phy based wol patch. Today, I found the issue by testing net-next tree.

For retransmitted packets, TCP needs to resort to using TCP timestamps for computing RTT samples. In the common case where the data and ACK fall in the same 1-millisecond interval, TCP senders with millisecond- granularity TCP timestamps compute a ca_rtt_us of 0. This ca_rtt_us of 0 propagates to rs->rtt_us. This value of 0 can cause performance problems for congestion control modules. For example, in BBR, the zero min_rtt sample can bring the min_rtt and BDP estimate down to 0, reduce snd_cwnd and result in a low throughput. It would be hard to mitigate this with filtering in the congestion control module, because the proper floor to apply would depend on the method of RTT sampling (using timestamp options or internally-saved transmission timestamps). This fix applies a floor of 1 for the RTT sample delta from TCP timestamps, so that seq_rtt_us, ca_rtt_us, and rs->rtt_us will be at least 1 * (USEC_PER_SEC / TCP_TS_HZ). Note that the receiver RTT computation in tcp_rcv_rtt_measure() and min_rtt computation in tcp_update_rtt_min() both already apply a floor of 1 timestamp tick, so this commit makes the code more consistent in avoiding this edge case of a value of 0.

Potentially overflowing expression (ts_freq << 16 and intgr << 16) declared as type u32 (32-bit unsigned) is evaluated using 32-bit arithmetic and then used in a context that expects an expression of type u64 (64-bit unsigned) which ultimately is used as 16-bit unsigned by typecasting to u16.

This adds full 802.1q VLAN support to the qca8k, allowing the use of vlan_filtering and more complicated bridging setups than allowed by basic port VLAN support. Tested with a number of untagged ports with separate VLANs and then a trunk port with all the VLANs tagged on it. v3: - Pull QCA8K_PORT_VID_DEF changes into separate cleanup patch - Reverse Christmas tree notation for variable definitions - Use untagged instead of tagged for consistency v2: - Return sensible errnos on failure rather than -1 (rmk) - Style cleanups based on Florian's feedback - Silently allow VLAN 0 as device correctly treats this as no tag Signed-off-by:

Kiran modifies the check for linearization and corrects the vsi_id mask value. Vignesh replaces the use of flow profile locks to RSS profile locks for RSS rule removal. Destroys flow profile lock on clearing XLT table and clears extraction sequence entries. Jesse adds some statistics and removes an unreported one. Brett allows for 2 queue configuration for VFs. Surabhi adds a check for failed allocation of an extraction sequence table. Tony updates the PTYPE lookup table and makes other trivial fixes.

commit c8729cac ("cxgb4: add ethtool n-tuple filter insertion") has removed checking control key for determining IP address types for TC-FLOWER rules, which causes all the rules being inserted to hardware to become IPv6 rule type always. So, add back the check to select the correct IP address type to extract and hence fix the correct rule type being inserted to hardware. Also, ethtool_rx_flow_key doesn't have any control key and instead directly sets the IPv4/IPv6 address keys. So, explicitly set the IP address type for ethtool n-tuple filters to reuse the same code.
