This patch adds support for the switchdev_port_attr_get() and
ndo_get_phys_port_name() methods for the PF and the VF-reps.
Using this support a user application can deduce that the PF
(when in the ESWITCH_SWDEV mode) and it's VF-reps form a switch.

This patch introduces the RX/TX and a simple netdev implementation
for VF-reps. The VF-reps use the RX/TX rings of the PF. For each VF-rep
the PF driver issues a VFR_ALLOC FW cmd that returns "cfa_code"
and "cfa_action" values. The FW sets up the filter tables in such
a way that VF traffic by default (in absence of other rules)
gets punted to the parent PF. The cfa_code value in the RX-compl
informs the driver of the source VF. For traffic being transmitted
from the VF-rep, the TX BD is tagged with a cfa_action value that
informs the HW to punt it to the corresponding VF.

This patch is a part of a patch-set that introduces support for
VF-reps in the bnxt_en driver. The driver registers eswitch mode
get/set methods with the devlink interface that allow a user to
enable SRIOV switchdev mode. When enabled, the driver registers
a VF-rep netdev object for each VF with the stack. This can
essentially bring the VFs unders the management perview of the
hypervisor and applications such as OVS.
The next patch in the series, adds the RX/TX routines and a slim
netdev implementation for the VF-reps.

The array data is only populated with valid information from userspace
if cmd != SIOCDEVPRIVATE, other cases the array contains garbage on
the stack. The subsequent switch statement acts on a subcommand in
data[0] which could be any garbage value if cmd is SIOCDEVPRIVATE which
seems incorrect to me. Instead, just return EOPNOTSUPP for the case
where cmd == SIOCDEVPRIVATE to avoid this issue.
As a side note, I suspect that the original intention of the code
was for this ioctl to work just for cmd == SIOCDEVPRIVATE (and the
current logic is reversed). However, I don't wont to change the current
semantics in case any userspace code relies on this existing behaviour.
