This series fixes a problem that was reported where encapsulated packets
do not have their encapsulation offload markers stripped off when being
decapsulated. This causes a significant performance drop if the packets
are later retransmitted.
Fixing this revealed two other bugs which are also addressed as prerequisites:
* GRO can aggregate packets for multiple layers of encapsulation which the
stack cannot properly handle.
* IPIP packets which are combined by GRO are not marked properly with their
GSO type.
Note that this is based off the net-next tree as the current target for
bug fixes.
v2: No code changes, just additional information in commit messages and
a new cover letter.
Jesse Gross (3):
ipip: Properly mark ipip GRO packets as encapsulated.
tunnels: Don't apply GRO to multiple layers of encapsulation.
tunnels: Remove encapsulation offloads on decap.
