    "content": "This patch assumes that the bnxt hardware will ignore existing IPv4/v6\nheader fields for length and checksum as well as the length and checksum\nfields for outer UDP and GRE headers.\n\nI have been told by Michael Chan that this is working.  Though this might\nbe somewhat redundant for IPv6 as they are forcing the checksum to be\ncomputed for all IPv6 frames that are offloaded.  A follow-up patch may be\nnecessary in order to fix this as it is essentially mangling the outer IPv6\nheaders to add a checksum where none was requested.\n\nSigned-off-by: Alexander Duyck <aduyck@mirantis.com>\n---\n drivers/net/ethernet/broadcom/bnxt/bnxt.c |    9 +++++++--\n 1 file changed, 7 insertions(+), 2 deletions(-)",
