Subject: octeontx2-pf: Fix TSOv6 offload
From: Sunil Goutham <sgoutham@xxxxxxxxxxx>
commit de678ca38861f2eb58814048076dcf95ed1b5bf9 upstream.
HW adds segment size to the payload length
in the IPv6 header. Fix payload length to
just TCP header length instead of 'TCP header
size + IPv6 header size'.
Fixes: 86d7476078b8 ("octeontx2-pf: TCP segmentation offload support")
