Jasvinder Singh April 27, 2020, 2:03 p.m. UTC
When sending request messages to data plane pipelines, the
caller must free the memory allocated to request message on
receiving error response.

Coverity Issues: 357676, 357680, 357681, 357682, 357690, 357693, 357711,
357722, 357725, 357734, 357739, 357743, 357747,357762, 357766, 357787

Fixes: 6d4d05402501 ("net/softnic: add command to read stats")
Fixes: 202905f3ee4d ("net/softnic: add command to create objects")
Fixes: ee19326a4b1e ("net/softnic: add command for pipeline table entries")
Fixes: 9bc0ce0ad17c ("net/softnic: add command for meter action")
Fixes: 2505030a8383 ("net/softnic: add command for TTL action")

Cristian,

Can you merge this and other Coverity fixes. They need to be cleared for DPDK 20.05.

there.
