From: Thomas Monjalon Date: Thu, 5 Apr 2018 15:33:21 +0000 (+0200) Subject: fix ethdev port id validation X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a9dbe1802226;p=dpdk.git fix ethdev port id validation Some DPDK applications wrongly assume these requirements: - no hotplug, i.e. ports are never detached - all allocated ports are available to the application Such application assume a valid port index is in the range [0..count[. There are three consequences when using such wrong design: - new ports having an index higher than the port count won't be valid - old ports being detached (RTE_ETH_DEV_UNUSED) can be valid Such mistake will be less common with growing hotplug awareness. All applications and examples inside this repository - except testpmd - must be fixed to use the function rte_eth_dev_is_valid_port.
