            Bug ID: 1693
           Summary: ring PMD rte_eth_from_ring does not do what is
                    expected
           Product: DPDK
           Version: 25.03
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev at dpdk.org
          Reporter: stephen at networkplumber.org
  Target Milestone: ---

The function rte_eth_from_ring does not really do what it says on the tin.
The programmer would expect that the ring passed would be used to make an
ethdev.
Instead the name is used as a seed to a new ring name ETH_RXTX0_XXXX.

Not sure if it ever did the right thing.

One would expect the passed in ring would become the ring used for the ethdev.
Instead the passed in ring is never used.
