To: david.marchand, jerinj; +Cc: dev, Pavan Nikhilesh
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add reassembly perf autotest for both ipv4 and ipv6 reassembly.
Each test is performed with vairable number of fragments per flow,
either ordered or unorderd fragments and interleaved flows.

v2 Changes
- Rebase to master, reduce memory consumption, set default mempool ops
to ring_mp_mc.

* [dpdk-dev] [PATCH v3] test: add reassembly perf test
2021-10-04 13:33 [dpdk-dev] [PATCH v2] test: add reassembly perf test pbhagavatula
@ 2021-10-04 14:23 ` pbhagavatula
0 siblings, 0 replies; 2+ messages in thread
From: pbhagavatula @ 2021-10-04 14:23 UTC (permalink / raw)
To: david.marchand, jerinj; +Cc: dev, Pavan Nikhilesh
From: Pavan Nikhilesh <pbhagavatula@marvell.com>
Add reassembly perf autotest for both ipv4 and ipv6 reassembly.
Each test is performed with variable number of fragments per flow,
either ordered or unordered fragments and interleaved flows.
Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com>
---
v3 Changes:
- Fix checkpatch issues.
v2 Changes
- Rebase to master, reduce memory consumption, set default mempool ops
to ring_mp_mc.
