For non-shared\nall the allocated resources are owned and managed by a single\nsession instance. No other applications have access to the\nresources owned by the non-shared session.  For a shared session,\nresources are shared between 2 applications.\n\nThe FW shared session can only be created by one application and\nshared by other apps. The host session that creates the FW shared\nsession is the creator.\n\nApplications can retrieve the reserved resources through a new API\ntf_get_session_resc_info.\n\nEach module supports two sessions, one is shared session, the other\nis non-shared session.\n\nSigned-off-by: Jay Ding <jay.ding@broadcom.com>\nSigned-off-by: Randy Schacher <stuart.schacher@broadcom.com>\nSigned-off-by: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>\nReviewed-by: Farah Smith <farah.smith@broadcom.com>\n---\n drivers/net/bnxt/hsi_struct_def_dpdk.h    | 281 +++++++++++++++++-----\n drivers/net/bnxt/tf_core/bitalloc.c       |  10 +-\n drivers/net/bnxt/tf_core/bitalloc.h       |   3 +-\n drivers/net/bnxt/tf_core/tf_core.c        | 105 ++++++++\n drivers/net/bnxt/tf_core/tf_core.h        | 177 +++++++++++++-\n drivers/net/bnxt/tf_core/tf_device.c      |  76 +++---\n drivers/net/bnxt/tf_core/tf_device.h      |  73 ++++++\n drivers/net/bnxt/tf_core/tf_device_p4.c   |   8 +\n drivers/net/bnxt/tf_core/tf_device_p58.c  |   8 +\n drivers/net/bnxt/tf_core/tf_em.h          |  17 ++\n drivers/net/bnxt/tf_core/tf_em_common.c   |  25 --\n drivers/net/bnxt/tf_core/tf_em_internal.c | 118 +++++----\n drivers/net/bnxt/tf_core/tf_identifier.c  |  89 +++----\n drivers/net/bnxt/tf_core/tf_identifier.h  |  16 ++\n drivers/net/bnxt/tf_core/tf_msg.c         | 223 ++++++++++++++---\n drivers/net/bnxt/tf_core/tf_msg.h         |  47 +++-\n drivers/net/bnxt/tf_core/tf_rm.c          | 277 ++++++++++++++++++++-\n drivers/net/bnxt/tf_core/tf_rm.h          |  34 +++\n drivers/net/bnxt/tf_core/tf_session.c     |  37 ++-\n drivers/net/bnxt/tf_core/tf_session.h     |  66 +++++\n drivers/net/bnxt/tf_core/tf_tbl.c         | 104 ++++----\n drivers/net/bnxt/tf_core/tf_tbl.h         |  17 ++\n drivers/net/bnxt/tf_core/tf_tcam.c        | 103 ++++----\n drivers/net/bnxt/tf_core/tf_tcam.h        |  16 ++\n drivers/net/bnxt/tf_core/tfp.c            |   6 +-\n drivers/net/bnxt/tf_core/tfp.h            |   3 +-\n 26 files changed, 1560 insertions(+), 379 deletions(-)",
