[PATCH v2 2/2] examples: use default mbuf burst size
pbhagavatula at marvell.com
pbhagavatula at marvell.com
Thu Apr 16 23:11:58 CEST 2026
From: Pavan Nikhilesh <pbhagavatula at marvell.com>
Replace hardcoded burst sizes with RTE_MBUF_BURST_SIZE_DEFAULT
to adapt to platform-specific optimal burst sizes.
Signed-off-by: Pavan Nikhilesh <pbhagavatula at marvell.com>
