[PATCH net-next 0/3] sfc: physical port ids

From: Edward Cree <hidden>
Date: 2017-01-10 16:22:40

This series brings our handling of ndo_get_phys_port_id and related
 interfaces into line with the behaviour of other drivers.

Bert Kenward (3):
  sfc: support ndo_get_phys_port_id even when !CONFIG_SFC_SRIOV
  sfc: implement ndo_get_phys_port_name
  sfc: stop setting dev_port

[PATCH net-next 1/3] sfc: support ndo_get_phys_port_id even when !CONFIG_SFC_SRIOV

From: Edward Cree <hidden>
Date: 2017-01-10 16:24:04

From: Bert Kenward <redacted>

There's no good reason why this should be an SRIOV-only thing.
Thus, also move it out of SRIOV-specific files.

[PATCH net-next 2/3] sfc: implement ndo_get_phys_port_name

From: Edward Cree <hidden>
Date: 2017-01-10 16:24:14

From: Bert Kenward <redacted>

Output is of the form p<port-number>.
Note that the port numbers don't necessarily map one-to-one to physical
 cages, partly because of 4x10G port modes on QSFP+ and partly because
 of hw/fw implementation details.

[PATCH net-next 3/3] sfc: stop setting dev_port

From: Edward Cree <hidden>
Date: 2017-01-10 16:24:40

From: Bert Kenward <redacted>

Setting dev_port changes the device names allocated by systemd. Any devices
with a dev_port >0 will (in default distro configurations) have a suffix of
"d<port-number>" appended.

This is not something done by other drivers, and causes confusion for users.
