[ upstream commit c0278f6e52399f7612f9f1a9d52434071ac49921 ]
[ upstream commit 41dfa14c9c6587dc934042c04ce7f86015acd608 ]
The HW only supports tunnel header parsing globally for supported tunnel
types. When a function uses one default VNIC to receive both the tunnel
and non-tunnel packets, applying the same stateless offload operation to
both tunnel and non-tunnel packets can cause problems in certain scenarios.
To workaround these problems, the firmware advertises no tunnel header
parsing capabilities to the driver using the HWRM_FUNC_QCAPS.
The driver must check this flag setting and accordingly not advertise
tunnel packet stateless offload capabilities to the stack.
If the device supports VXLAN, GRE, IPIP and GENEVE tunnel parsing,
then reports RX_OFFLOAD_OUTER_IPV4_CKSUM, RX_OFFLOAD_OUTER_UDP_CKSUM
and TX_OFFLOAD_OUTER_IPV4_CKSUM in the Rx/Tx offload capabilities of
the device.
Also, advertise tunnel TSO capabilities based on FW support.
