[dpdk-dev] [PATCH v2 0/3] eal: allow hotplug to skip an already probed device

[Thomas Monjalon <thomas@monjalon.net>]

This is a follow-up of an idea presented at Dublin
during the "hotplug talk".

The idea is to ease probing of range of ports attached
to the same rte_device.
I becomes possible to allow probing again the same device
but with a bigger range of ports in the devargs.

Instead of adding a parameter to the hotplug functions, as in the RFC,
the check of an already probed device is moved to the PMDs.
It gives flexibility to drivers for managing range of ports.
