[dpdk-dev] [PATCH v4 11/19] net/ena: fix parsing of large LLQ header devarg

Michal Krawczyk mk at semihalf.com
Tue May 11 08:45:46 CEST 2021


From: Igor Chauskin <igorch at amazon.com>

The code incorrectly checked the return value of comparison when parsing
the argument key name. The return value of strcmp should be compared
to 0 to identify a match.

Fixes: 8a7a73f26cc9 ("net/ena: support large LLQ headers")
