6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sridhar Samudrala <sridhar.samudrala@xxxxxxxxx>
[ Upstream commit 69ab25a74e2df53edc2de4acfce0a484bdb88155 ]
Handle rsc packet with a single segment same as a multi
segment rsc packet so that CHECKSUM_PARTIAL is set in the
skb->ip_summed field. The current code is passing CHECKSUM_NONE
resulting in TCP GRO layer doing checksum in SW and hiding the
issue. This will fail when using dmabufs as payload buffers as
skb frag would be unreadable.
