2018-05-23brcmfmac: add debugfs entry for reading firmware capabilitiesRafał Miłecki1-0/+36
This allows reading all capabilities as reported by a firmware. They are printed using native (raw) names, just like developers like it the most. It's how firmware reports support for various features, e.g. supported modes, supported standards, power saving details, max BSS-es. Access to all that info is useful for trying new firmwares, comparing them and debugging features AKA bugs.

2018-05-19net: ip6_gre: fix tunnel metadata device sharing.William Tu1-22/+79
Currently ip6gre and ip6erspan share single metadata mode device, using 'collect_md_tun'. Thus, when doing: ip link add dev ip6gre11 type ip6gretap external ip link add dev ip6erspan12 type ip6erspan external RTNETLINK answers: File exists simply fails due to the 2nd tries to create the same collect_md_tun. The patch fixes it by adding a separate collect md tunnel device for the ip6erspan, 'collect_md_tun_erspan'. As a result, a couple of places need to refactor/split up in order to distinguish ip6gre and ip6erspan. First, move the collect_md check at ip6gre_tunnel_{unlink,link} and create separate function {ip6gre,ip6ersapn}_tunnel_{link_md,unlink_md}. Then before link/unlink, make sure the link_md/unlink_md is called. Finally, a separate ndo_uninit is created for ip6erspan. Tested it using the samples/bpf/test_tunnel_bpf.sh.

2018-05-19sh_eth: add R8A77980 supportSergei Shtylyov2-0/+45
Finally, add support for the DT probing of the R-Car V3H (AKA R8A77980) -- it's the only R-Car gen3 SoC having the GEther controller -- others have only EtherAVB...

2018-05-19net: mvpp2: Add missing VLAN tag detectionMaxime Chevallier1-0/+3
Marvell PPv2 Header Parser sets some bits in the 'result_info' field in each lookup iteration, to identify different packet attributes such as DSA / VLAN tag, protocol infos, etc. This is used in further classification stages in the controller. It's the DSA tag detection entry that is in charge of detecting when there is a single VLAN tag. This commits adds the missing update of the result_info in this case.

2018-05-19devlink: introduce a helper to generate physical port namesJiri Pirko2-0/+42
Each driver implements physical port name generation by itself. However as devlink has all needed info, it can easily do the job for all its users. So implement this helper in devlink. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-05-19devlink: extend attrs_set for setting port flavoursJiri Pirko5-4/+24
Devlink ports can have specific flavour according to the purpose of use. This patch extend attrs_set so the driver can say which flavour port has. Initial flavours are: physical, cpu, dsa User can query this to see right away what is the purpose of each port. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.
