            Bug ID: 1431
           Summary: net/tap: treats kernel device full as error
           Product: DPDK
           Version: 24.03
          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 TAP PMD treats the kernel returning EAGAIN because its queue is full as an
error. This is incorrect, the PMD should just quietly return the number of
mbufs successfully sent.
