[Anoob] Checkpatch warnings are false positives. I'll try to work around couple of them. Rest we may need to ignore.

[Anoob] Lib PDCP would handle such cases. Even if a_xfrm is non NULL but is NULL auth, it is lib PDCP which would add zeroized digest. And a_xfrm == NULL is also treated as NULL auth generally. The comment above this explains the same. Idea is to have lib PDCP handle all possible cases rather than putting too much restrictions on both app & PMD.

[Anoob] I do not think so. I checked rte_ethdev.h, rte_flow.h etc and all APIs are returning negative values in case of errors.

[Anoob] Validation happens when we create session. Please check,
pdcp: add crypto session create and destroy

[Anoob] HFN is part of pdcp_xfrm which is defined in rte_security. Lib PDCP allows user to specify complete 32 bit count value using rte_pdcp_entity_conf.count. Since HFN is also used to construct 32 bit count value, having two ways to set count would be misleading. Hence lib PDCP would enforce that application does not set this value.
