2018-05-25cxgb4/cxgb4vf: Notify link changes to OS-dependent codeArjun Vynipadath1-0/+3
We have a confusion of two different abstractions in the Common Code: Physical Link (Port) and Logical Network Interface (Virtual Interface), and we haven't been properly managing the state of the intersection of those two abstractions. On the one hand we have the Physical state of the Link -- up or down -- and on the other we have the logical state of the VI, enabled or not. {ethN} refers to both the Physical and Logical State. In this case, ifconfig only affects/interrogates the Logical State of a VI, and ethtool only deals with the Physical State. And these are different. So, just because we disable the VI, we don't really want to change the Physical Link Up/Down state. Thus, the previous hack to set "lc->link_ok = 0" when we disable a VI is completely incorrect. Where we get into trouble is where the Physical Link State and the Logical VI State cross swords. And that happens in t4_handle_get_port_info() where we need to manage/safe the Physical Link State, but we also need to know when the Logical VI State has changed and pass that back up to the OS-dependent Driver routine t4_os_link_changed() which is concerned about the Logical Interface. So we enable a VI and that causes Firmware to send us a new Port Information message, but if none of the Physical Link State particulars have changed, we don't call t4_os_link_changed(). This fix uses the existing OS Contract APIs for the Common Code to inform the OS-dependent portion of the Host Driver when the "Link" (really Logical Network Interface) is "up" or "down". A new API t4_enable_pi_params() is added which calls t4_enable_vi_params() and, if that is successful, then calls back to the OS Contract API t4_os_link_changed() notifying the OS-dependent layer of the potential Link State change.

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.

Pull networking updates from David Miller: "Reasonably busy this cycle, but perhaps not as busy as in the 4.12 merge window: 1) Several optimizations for UDP processing under high load from Paolo Abeni. 2) Support pacing internally in TCP when using the sch_fq packet scheduler for this is not practical. From Eric Dumazet. 3) Support mutliple filter chains per qdisc, from Jiri Pirko. 4) Move to 1ms TCP timestamp clock, from Eric Dumazet. 5) Add batch dequeueing to vhost_net, from Jason Wang. 6) Flesh out more completely SCTP checksum offload support, from Davide Caratti. 7) More plumbing of extended netlink ACKs, from David Ahern, Pablo Neira Ayuso, and Matthias Schiffer. 8) Add devlink support to nfp driver, from Simon Horman. 9) Add RTM_F_FIB_MATCH flag to RTM_GETROUTE queries, from Roopa Prabhu. 10) Add stack depth tracking to BPF verifier and use this information in the various eBPF JITs. From Alexei Starovoitov. 11) Support XDP on qed device VFs, from Yuval Mintz. 12) Introduce BPF PROG ID for better introspection of installed BPF programs. From Martin KaFai Lau. 13) Add bpf_set_hash helper for TC bpf programs, from Daniel Borkmann. 14) For loads, allow narrower accesses in bpf verifier checking, from Yonghong Song. 15) Support MIPS in the BPF selftests and samples infrastructure, the MIPS eBPF JIT will be merged in via the MIPS GIT tree. From David Daney. 16) Support kernel based TLS, from Dave Watson and others. 17) Remove completely DST garbage collection, from Wei Wang. 18) Allow installing TCP MD5 rules using prefixes, from Ivan Delalande. 19) Add XDP support to Intel i40e driver, from Björn Töpel 20) Add support for TC flower offload in nfp driver, from Simon Horman, Pieter Jansen van Vuuren, Benjamin LaHaise, Jakub Kicinski, and Bert van Leeuwen. 21) IPSEC offloading support in mlx5, from Ilan Tayari. 22) Add HW PTP support to macb driver, from Rafal Ozieblo. 23) Networking refcount_t conversions, From Elena Reshetova. 24) Add sock_ops support to BPF, from Lawrence Brako. This is useful for tuning the TCP sockopt settings of a group of applications, currently via CGROUPs" * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1899 commits) net: phy: dp83867: add workaround for incorrect RX_CTRL pin strap dt-bindings: phy: dp83867: provide a workaround for incorrect RX_CTRL pin strap cxgb4: Support for get_ts_info ethtool method cxgb4: Add PTP Hardware Clock (PHC) support cxgb4: time stamping interface for PTP nfp: default to chained metadata prepend format nfp: remove legacy MAC address lookup nfp: improve order of interfaces in breakout mode net: macb: remove extraneous return when MACB_EXT_DESC is defined bpf: add missing break in for the TCP_BPF_SNDCWND_CLAMP case bpf: fix return in load_bpf_file mpls: fix rtm policy in mpls_getroute net, ax25: convert ax25_cb.refcount from atomic_t to refcount_t net, ax25: convert ax25_route.refcount from atomic_t to refcount_t net, ax25: convert ax25_uid_assoc.refcount from atomic_t to refcount_t net, sctp: convert sctp_ep_common.refcnt from atomic_t to refcount_t net, sctp: convert sctp_transport.refcnt from atomic_t to refcount_t net, sctp: convert sctp_chunk.refcnt from atomic_t to refcount_t net, sctp: convert sctp_datamsg.refcnt from atomic_t to refcount_t net, sctp: convert sctp_auth_bytes.refcnt from atomic_t to refcount_t ...

2017-06-23cxgb4: Use Firmware params to get buffer-group mapArjun Vynipadath1-1/+9
Buffer group mappings can be obtained using FW_PARAMs cmd for newer FW. Since some of the bg_maps are obtained in atomic context, created another t4_query_params_ns(), that wont sleep when awaiting mbox cmd completion.

2017-06-23cxgb4: Update T6 Buffer Group and Channel MappingsArjun Vynipadath1-1/+2
We were using t4_get_mps_bg_map() for both t4_get_port_stats() to determine which MPS Buffer Groups to report statistics on for a given Port, and also for t4_sge_alloc_rxq() to provide a TP Ingress Channel Congestion Map. For T4/T5 these are actually the same values (because they are ~somewhat~ related), but for T6 they should return different values (T6 has Port 0 associated with MPS Buffer Group 0 (with MPS Buffer Group 1 silently cascading off) and Port 1 is associated with MPS Buffer Group 2 (with 3 cascading off)).
