There is no point in updating the MAC address of a switch interface each time the link state changes, this only needs to happen in case the endpoint changes (the switch interface is [dis]connected from/to a MAC). Just move the call to dpaa2_switch_port_set_mac_addr() under DPSW_IRQ_EVENT_ENDPOINT_CHANGED. Reviewed-by:

Add SW IRQ coalescing based on hrtimers for TX and RX data path which can be enabled by ethtool commands: - RX coalescing ethtool -C eth1 rx-usecs 50 - TX coalescing can be enabled per TX queue - by default enables coalesing for TX0 ethtool -C eth1 tx-usecs 50 - configure TX0 ethtool -Q eth0 queue_mask 1 --coalesce tx-usecs 100 - configure TX1 ethtool -Q eth0 queue_mask 2 --coalesce tx-usecs 100 - configure TX0 and TX1 ethtool -Q eth0 queue_mask 3 --coalesce tx-usecs 100 --coalesce tx-usecs 100 show configuration for TX0 and TX1: ethtool -Q eth0 queue_mask 3 --show-coalesce Comparing to gro_flush_timeout and napi_defer_hard_irqs, this patch allows to enable IRQ coalesing for RX path separately.

Add driver support for viewing / changing the MAC Merge sublayer parameters and seeing the verification state machine's current state via ethtool. As hardware does not support interrupt notification for verification events we resort to polling on link up. On link up we try a couple of times for verification success and if unsuccessful then give up. The Frame Preemption feature is described in the Technical Reference Manual [1] in section: 12.3.1.4.6.7 Intersperced Express Traffic (IET – P802.3br/D2.0) Due to Silicon Errata i2208 [2] we set limit min IET fragment size to 124 (excluding 4 bytes mCRC).

This patch adds MQPRIO Qdisc offload in full 'channel' mode which allows not only setting up pri:tc mapping, but also configuring TX shapers (rate-limiting) on external port FIFOs. The MQPRIO Qdisc offload is expected to work with or without VLAN/priority tagged packets. The CPSW external Port FIFO has 8 Priority queues. The rate-limit can be set for each of these priority queues. Which Priority queue a packet is assigned to depends on PN_REG_TX_PRI_MAP register which maps header priority to switch priority. The header priority of a packet is assigned via the RX_PRI_MAP_REG which maps packet priority to header priority. The packet priority is either the VLAN priority (for VLAN tagged packets) or the thread/channel offset. For simplicity, we assign the same priority queue to all queues of a Traffic Class so it can be rate-limited correctly. Configuration example: ethtool -L eth1 tx 5 ethtool --set-priv-flags eth1 p0-rx-ptype-rrobin off tc qdisc add dev eth1 parent root handle 100: mqprio num_tc 3 \ map 0 0 1 2 0 0 0 0 0 0 0 0 0 0 0 0 \ queues 1@0 1@1 1@2 hw 1 mode channel \ shaper bw_rlimit min_rate 0 100mbit 200mbit max_rate 0 101mbit 202mbit tc qdisc replace dev eth2 handle 100: parent root mqprio num_tc 1 \ map 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 queues 1@0 hw 1 ip link add link eth1 name eth1.100 type vlan id 100 ip link set eth1.100 type vlan egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7 In the above example two ports share the same TX CPPI queue 0 for low priority traffic. 3 traffic classes are defined for eth1 and mapped to: TC0 - low priority, TX CPPI queue 0 -> ext Port 1 fifo0, no rate limit TC1 - prio 2, TX CPPI queue 1 -> ext Port 1 fifo1, CIR=100Mbit/s, EIR=1Mbit/s TC2 - prio 3, TX CPPI queue 2 -> ext Port 1 fifo2, CIR=200Mbit/s, EIR=2Mbit/s Signed-off-by:

Some devices have errata due to which they cannot report ETH_ZLEN (60) in the rx-min-frag-size. This was foreseen of course, and lldpad has logic that when we request it to advertise addFragSize 0, it will round it up to the lowest value that is _actually_ supported by the hardware. The problem is that the selftest expects lldpad to report back to us the same value as we requested. Make the selftest smarter by figuring out on its own what is a reasonable value to expect.

Add a variable RUN_IN_NETNS if the user wants to run all the selected tests in namespace in parallel. With this, we can save a lot of testing time. Note that some tests may not fit to run in namespace, e.g. net/drop_monitor_tests.sh, as the dwdump needs to be run in init ns. I also added another parameter -p to make all the logs reported separately instead of mixing them in the stdout or output.log. Nit: the NUM in run_one is not used, rename it to test_num. Acked-by:

Sockets in bhash are also linked to bhash2, but TIME_WAIT sockets are linked separately in tb2->deathrow. Let's replace tb->owners iteration in inet_csk_bind_conflict() with two iterations over tb2->owners and tb2->deathrow. This can be done safely under bhash's lock because socket insertion/ deletion in bhash2 happens with bhash's lock held. Note that twsk_for_each_bound_bhash() will be removed later. Signed-off-by:

bhash2 added a new member sk_bind2_node in struct sock to link sockets to bhash2 in addition to bhash. bhash is still needed to search conflicting sockets efficiently from a port for the wildcard address. However, bhash itself need not have sockets. If we link each bhash2 bucket to the corresponding bhash bucket, we can iterate the same set of the sockets from bhash2 via bhash. This patch links bhash2 to bhash only, and the actual use will be in the later patches. Finally, we will remove sk_bind2_node. Signed-off-by:

Later, we no longer link sockets to bhash. Instead, each bhash2 bucket is linked to the corresponding bhash bucket. Then, we pass the bhash bucket to bhash2 allocation functions as tb. However, tb is already used in inet_bind2_bucket_create() and inet_bind2_bucket_init() as the bhash2 bucket. To make the following diff clear, let's use tb2 for the bhash2 bucket there.

inet_bind2_bucket_addr_match() and inet_bind2_bucket_match_addr_any() are called for each bhash2 bucket to check conflicts. Thus, we call ipv6_addr_any() and ipv6_addr_v4mapped() over and over during bind(). Let's avoid calling them by saving the address type in inet_bind2_bucket. Signed-off-by:

Kuniyuki Iwashima authored
In bhash2, IPv4/IPv6 addresses are saved in two union members, which complicate address checks in inet_bind2_bucket_addr_match() and inet_bind2_bucket_match_addr_any() considering uninitialised memory and v4-mapped-v6 conflicts. Let's simplify that by saving IPv4 address as v4-mapped-v6 address and defining tb2.rcv_saddr as tb2.v6_rcv_saddr.s6_addr32[3]. Then, we can compare v6 address as is, and after checking v4-mapped-v6, we can compare v4 address easily. Also, we can remove tb2->family. Note these functions will be further refactored in the next patch. Signed-off-by:

While checking port availability in bind() or listen(), we used only bhash for all v4-mapped-v6 addresses. But there is no good reason not to use bhash2 for v4-mapped-v6 non-wildcard addresses. Let's do it by returning true in inet_use_bhash2_on_bind(). Then, we also need to add a test in inet_bind2_bucket_match_addr_any() so that ::ffff:X.X.X.X will match with 0.0.0.0. Note that sk->sk_rcv_saddr is initialised for v4-mapped-v6 sk in __inet6_bind(). Signed-off-by:
