[PATCH 00/10] require checking ethdev get return value

[Stephen Hemminger <stephen@networkplumber.org>]

Several places flagged by Coverity and Codeql are from code that
calls rte_eth_dev_info_get() but does not check the return value.
If rte_eth_dev_info_get() returns an error, the device info is garbage.

This patch series uses the function attribute to force code
to check the result or there will be a compiler warning.

The series is ordered to fix the current warnings first
before enabling it.

Stephen Hemminger (10):
  app/test: remove redundant call
  net/memif: check return value from rte_eth_dev_info_get
  graph: check return value from rte_eth_dev_info_get
  examples/ethtool: handle devices without registers
  examples/l3fwd: check return value from ethdev info
  examples/ntb: always check return value
  examples/pipeline: check return value of ethdev functions
  examples/qos_sched: check return value from rte_eth_link_get
  ethdev: check return value from rte_eth_dev_info_get
  ethdev: require checking results of info_get functions
