Since commit 0f06a678 ("samples: Add an IPv6 '-6' option to the pktgen scripts") the newer pktgen_sampleXX script does show howto use IPv6 with pktgen. Thus, there is no longer a reason to keep the older sample scripts around. Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This script simply does: * Detect $DEV's NUMA node belonging. * Bind each thread (processor of NUMA locality) with each $DEV queue's irq affinity, 1:1 mapping. * How many '-t' threads input determines how many queues will be utilized. If '-f' designates first cpu id, then offset in the NUMA node's cpu list. (Changes by Jesper: allow changing count from cmdline via '-n') Signed-off-by: Robert Hoo <robert.hu@intel.com> Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: David S.

Rahul Lakkireddy says: ==================== cxgb4: add hash-filter support to tc-flower offload This series of patches add support to create hash-filters; a.k.a exact-match filters, to tc-flower offload. T6 supports creating ~500K hash-filters in hw and can theoretically be expanded up to ~1 million. Patch 1 fetches and saves the configured hw filter tuple field shifts and filter mask. Patch 2 initializes the driver to use hash-filter configuration. Patch 3 adds support to create hash filters in hw. Patch 4 adds support to delete hash filters in hw. Patch 5 adds support to retrieve filter stats for hash filters. Patch 6 converts the flower table to use rhashtable instead of static hlist. Patch 7 finally adds support to create hash filters via tc-flower offload. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

T6 supports ~500K hash filters and can theoretically climb up to ~1 million hash filters. Preallocated hash table is not efficient in terms of memory usage. So, use rhashtable instead which gives the flexibility to grow based on usage.

Add support to create hash (exact-match) filters based on the value of 'hash' field in ch_filter_specification. Allocate SMT/L2T entries if DMAC-rewrite/SMAC-rewrite is requested. Allocate CLIP entry in case of IPv6 filter. Use cpl_act_open_req[6] to send hash filter create request to hw. Also, the filter tuple is calculated as part of sending this request. Hash-filter reply is processed on getting cpl_act_open_rpl. In case of success, various bits/fields in filter-tcb are set per filter requirement, such as enabling filter hitcnts, and/or various header rewrite operations, such as VLAN-rewrite, NAT or (L3/L4)-rewrite, and SMAC/DMAC-rewrite. In case of failure, clear the filter entry and release any hw resources occupied by it. The patch also moves the functions set_tcb_field, set_tcb_tflag and configure_filter_smac towards beginning of file.

The chip flood broadcast and unknown multicast frames. On receive set skb->offload_fwd_mark to prevent the SW from flooding to the same ports. One exception: Because the ALR is set up to forward STP BPDUs only to CPU, the SW bridge should flood STP BPDUs if local STP is not enabled.

lan9303_xmit_use_arl() introduced in previous patch set is wrong. The chip flood broadcast and unknown multicast frames. The effect is that broadcasts and multicasts are duplicated on egress. It is not possible to configure the chip to direct unknown multicasts to CPU port only. This means that only unicast frames can be transmitted using ALR lookup.

David reported breakages of VRF scenarios due to the commit 6e617de8 ("net: avoid a full fib lookup when rp_filter is disabled."): the local addresses based test is too strict when VRFs are in place. With this change we fall-back to a full lookup when custom fib rules are in place; so that we address the VRF use case and possibly other similar issues in non trivial setups. v1 -> v2: - fix build breakage when CONFIG_IP_MULTIPLE_TABLES is not defined, reported by the kbuild test robot Reported-by: David Ahern <dsahern@gmail.com> Fixes: 6e617de8 ("net: avoid a full fib lookup when rp_filter is disabled.")

I have to mention that I did not implement any unit test. If someone has any suggestions on how I could test this piece of code it'd be greatly appreciated.

Changes in v3: - Update subject for both patches. - Add this cover letter as suggested by David Miller. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
