[dpdk-dev] [PATCH v2 2/2] test/compress: im buffer too small - add unit tests

[Akhil Goyal]

Hi Fiona/Adam,

> This patch adds a new test suite for verification of the "internal
> QAT IM buffer too small" case handling. These unit tests are
> specific to the QAT PMD only - that's why they are contained in
> a separate test suite.

Why do we need to have separate testsuite for QAT?
Can't we have a single one and based on capability of the driver,
Determine which tests need to be skipped in case they are not supported.
This would create a mess in the longer run just like cryptodev.

Please fix this, we cannot take this patch as is.
