This is inline with other Tx offloads\nrequirements such as L3 checksum, L4 checksum offload, etc,\nwhere mbuf.l2_len, mbuf.l3_len etc, needs to be set for HW to be\nable to generate checksum. Since Inline IPSec is also such a Tx\noffload, some PMD's at least need mbuf.l2_len to be valid to\nfind L3 header and perform Outbound IPSec processing.\n\nHence, this patch updates documentation to enforce setting\nmbuf.l2_len while setting PKT_TX_SEC_OFFLOAD in mbuf.ol_flags\nfor Inline IPSec Crypto / Protocol offload processing to\nwork on Tx.\n\nSigned-off-by: Nithin Dabilpuram <ndabilpuram@marvell.com>\n---\n doc/guides/nics/features.rst | 2 ++\n lib/mbuf/rte_mbuf_core.h | 2 ++\n 2 files changed, 4 insertions(+)", "diff": "diff --git a/doc/guides/nics/features.rst b/doc/guides/nics/features.rst\nindex a96e12d..4fce8cd 100644\n--- a/doc/guides/nics/features.rst\n+++ b/doc/guides/nics/features.rst\n@@ -430,6 +430,7 @@ of protocol operations.
