Subject: net/cnxk: add inline IPsec telemetry for CN9K
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=41cc645c214fe9ab5f12a2334cffa353870ac0b9;p=dpdk.git

net/cnxk: add inline IPsec telemetry for CN9K

Adds telemetry function to get information about inline
outbound and inline inbound SA's. The function takes port id
as input. Some fields in the structures roc_onf_ipsec_outb_sa
and roc_onf_ipsec_inb_sa are returned as output.
