2017-07-05dt-bindings: phy: dp83867: provide a workaround for incorrect RX_CTRL pin strapMurali Karicheri1-0/+7
The data manual for DP83867IR/CR, SNLS484E[1], revised march 2017, advises that strapping RX_DV/RX_CTRL pin in mode 1 and 2 is not supported (see note below Table 5 (4-Level Strap Pins)). It further advises that if a board has this pin strapped in mode 1 and mode 2, then to ensure proper operation of the PHY, a software workaround must be implemented. Since it is not possible to detect in software if RX_DV/RX_CTRL pin is incorrectly strapped, add a device-tree property for the board to advertise this and allow corrective action in software.

2017-07-05nfp: default to chained metadata prepend formatJakub Kicinski1-1/+8
ABI 4.x introduced the chained metadata format and made it the only one possible. There are cases, however, where the old format is preferred - mostly to make interoperation with VFs using ABI 3.x easier for the datapath. In ABI 5.x we allowed for more flexibility by selecting the metadata format based on capabilities. The default was left to non-chained. In case of fallback traffic, there is no capability telling the driver there may be chained metadata. With a very stripped- -down FW the default old metadata format would be selected making the driver drop all fallback traffic. This patch changes the default selection in the driver. It should not hurt with old firmwares, because if they don't advertise RSS they will not produce metadata anyway. New firmwares advertising ABI 5.x, however, can depend on the driver defaulting to chained format.

2017-07-05nfp: remove legacy MAC address lookupJakub Kicinski4-34/+8
The legacy MAC address lookup doesn't work well with breakout cables. We are probably better off picking random addresses than the wrong ones in the theoretical scenario where management FW didn't tell us what the port config is.

2017-07-05nfp: improve order of interfaces in breakout modeJakub Kicinski3-14/+12
For historical reasons we enumerate the vNICs in order. This means that if user configures breakout on a multiport card, the first interface of the second port will have its MAC address changed. What's worse, when moved from static information (HWInfo) to using management FW (NSP), more features started depending on the port ids. Right now in case of breakout first subport of the second port and second subport of the first port will have their link info swapped. Revise the ordering scheme so that first subport maintains its address. Side effect of this change is that we will use base lane ids in devlink (i.e. 40G ports will be 4 ids apart), e.g.: pci/0000:04:00.0/0: type eth netdev p6p1 pci/0000:04:00.0/4: type eth netdev p6p2 Note that behaviour of phys_port_id is not changed since there is a separate id number for the subport there.

2017-07-05bpf: fix return in load_bpf_fileLawrence Brakmo1-2/+6
The function load_bpf_file ignores the return value of load_and_attach(), so even if load_and_attach() returns an error, load_bpf_file() will return 0. Now, load_bpf_file() can call load_and_attach() multiple times and some can succeed and some could fail.

2017-07-04net, decnet: convert dn_fib_info.fib_clntref from atomic_t to refcount_tReshetova, Elena2-5/+6
refcount_t type and corresponding API should be used instead of atomic_t when the variable is used as a reference counter. This allows to avoid accidental refcounter overflows that might lead to use-after-free situations.
