Hi! This series brings port flavours for SR-IOV NICs.
First patch reshuffles nfp port registration to make the port info available at netdev registration time. Next the VF and PF port flavours are added to the core and the nfp driver. The existing port information (split) is now physical port-specific. The currently deployed NFPs have a single PF per PCIe link which means multiport cards have multiple logical ports (netdevs) per function. This forces us to add a notion of a PCIe subport (implemented in patches 4 and 5). With that in place nfp driver can now switch to using the devlink_port_get_phys_port_name() helper (patch 6). Next two patches add a notion of a peer netdev, this is the netdev "on the other side of the link". It can be used to inform users which PF and VF corresponds to which port/"representor" without the need for bus info parsing. Last but not least - I fix some kdoc warnings :) Jakub Kicinski (8): nfp: split devlink port init from registration devlink: add PF and VF port flavours nfp: register devlink ports of all reprs devlink: allow subports on devlink PCI ports nfp: switch to devlink_port_get_phys_port_name() devlink: introduce port's peer netdevs nfp: expose PF peer netdevs devlink: fix kdoc drivers/net/ethernet/netronome/nfp/abm/main.c | 1 + .../net/ethernet/netronome/nfp/flower/main.c | 1 + .../net/ethernet/netronome/nfp/nfp_devlink.c | 60 ++++++- .../net/ethernet/netronome/nfp/nfp_net_main.c | 17 +- .../net/ethernet/netronome/nfp/nfp_net_repr.c | 16 +- drivers/net/ethernet/netronome/nfp/nfp_port.c | 33 +--- drivers/net/ethernet/netronome/nfp/nfp_port.h | 4 + include/net/devlink.h | 41 ++++- include/uapi/linux/devlink.h | 9 ++ net/core/devlink.c | 153 +++++++++++++++--- 10 files changed, 268 insertions(+), 67 deletions(-) -- 2.19.2
