[PATCH net-next 0/3] pds_core: small code updates

[Shannon Nelson]

These are a few little code touch ups for a kdoc complaint,
quicker error detection, and a cleaner initialization.

[PATCH net-next 2/3] pds_core: smaller adminq poll starting interval

[Shannon Nelson]

Shorten the adminq poll starting interval in order to notice
any transaction errors more quickly.

It might be nice to add a bit more colour to what sort of scenarios
this helps. But that isn't a hard requirement from my side.

[PATCH net-next 3/3] pds_core: init viftype default in declaration

[Shannon Nelson]

Initialize the .enabled field of the FWCTL viftype default in
the declaration rather than as a bit of code as it is always
to be enabled and needs no logic around it.
