That will be moved to drivers/net/octeontx2 as is. The routines which are doing qp_add & qp_remove would be moved to common (discussed below). Otherwise, the rest should remain as is. If Jerin/Akhil wants further isolation, please do share specifics. Almost all functions in otx2_security.c is dereferencing 'rte_eth_dev'. So having (void *) will not help. >> >> The functions in otx2_security.c is calling inline functions in otx2_ipsec_fp.h (which has lower level implementations of session create etc).
