THanks Steven for the quick response. I want to enable EAL module
(complete logging at debug level ) only during bootup of fastpath. Once
bootup is done, i want to move this module log-level to default/ original.
Currently I'm using --log-level='.*',8 along with
./sources/fp/common/fp-var.h [ #define FP_LOG_DEFAULT FP_LOG_DEBUG ]
instead of [ #define FP_LOG_DEFAULT FP_LOG_ERR ]. refer below snip
<snip>
-#define FP_LOG_DEFAULT FP_LOG_ERR
+#define FP_LOG_DEFAULT FP_LOG_DEBUG
The problem is its throwing all the other debug messages like this after
fastpath started. Any way to disable below message <snip3> and only log
bootup of EAL debug messages alone ?
REgards,
Shanmugasundaram M
