<pre class="bz_comment_text">This was addressed in 24.11 by increasing the size of RTE_MP_MAX_FD_NUM to the
kernel limit (253)

ipc: increase file descriptor maximum number
The TAP and XDP driver both are limited to only 8 queues because of the
small limit imposed by EAL.
Increase the limit now, since this release allows changing ABI.
