* net_sched: remove list_head from tc_actionCong Wang2018-08-211-4/+2
| | | | | | | | | | | | After commit 90b73b77d08e, list_head is no longer needed. Now we just need to convert the list iteration to array iteration for drivers.

The max IRQ count is checked when re-initializing the IRQ vectors and this can happen multiple times during ifup or ethtool -L. If the max IRQ is reduced and the RDMA driver is operational, we may not initailize IRQs correctly. This problem shows up on VFs with very small number of MSIX. There is no other logic that relies on the IRQ count excluding the ones used by RDMA. So we fix it by just removing the call to subtract or add the IRQs used by RDMA.

The main changes are: 1) Various different arm32 JIT improvements in order to optimize code emission and make the JIT code itself more robust, from Russell. 2) Support simultaneous driver and offloaded XDP in order to allow for advanced use-cases where some work is offloaded to the NIC and some to the host. Also add ability for bpftool to load programs and maps beyond just the cgroup case, from Jakub. 3) Add BPF JIT support in nfp for multiplication as well as division. For the latter in particular, it uses the reciprocal algorithm to emulate it, from Jiong. 4) Add BTF pretty print functionality to bpftool in plain and JSON output format, from Okash. 5) Add build and installation to the BPF helper man page into bpftool, from Quentin. 6) Add a TCP BPF callback for listening sockets which is triggered right after the socket transitions to TCP_LISTEN state, from Andrey. 7) Add a new cgroup tree command to bpftool which iterates over the whole cgroup tree and prints all attached programs, from Roman. 8) Improve xdp_redirect_cpu sample to support parsing of double VLAN tagged packets, from Jesper. ==================== Signed-off-by: David S.

Subsequently drivers were also allowed to report back attachment flags (prog_flags), and since nowadays only programs attached will XDP_FLAGS_HW_MODE can get offloaded, we can tell the attachment mode from the flags driver reports. Remove prog_attached member.

The existing solution currently requires that we use ndo_select_queue in the transmit path if we want to associate specific Tx queues with a given MACVLAN interface. In order to get away from this we need to repurpose the tc_to_txq array and XPS pointer for the MACVLAN interface and use those as a means of accessing the queues on the lower device. As a result we cannot offload a device that is configured as multiqueue, however it doesn't really make sense to configure a macvlan interfaced as being multiqueue anyway since it doesn't really have a qdisc of its own in the first place. The big changes in this set are: Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN Disable XPS for single queue devices Replace accel_priv with sb_dev in ndo_select_queue Add sb_dev parameter to fallback function for ndo_select_queue Consolidated ndo_select_queue functions that appeared to be duplicates ==================== Signed-off-by: David S.

The only cases where we cannot are the cases where we might be dealing with either an upper device or a driver that would have configured things to support an sb_dev itself. The only driver that has any significant change in this patch set should be ixgbe as we can drop the redundant functionality that existed in both the ndo_select_queue function and the fallback function that was passed through to us.

| |/ / / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes it so that instead of passing a void pointer as the accel_priv we instead pass a net_device pointer as sb_dev. Making this change allows us to pass the subordinate device through to the fallback function eventually so that we can keep the actual code in the ndo_select_queue call as focused on possible on the exception cases.
