sum_needed and cptse flags are received from the guest within each
transmit data descriptor. They are not part of the offload context;
instead, they determine how to apply a previously received context to
the packet being transmitted:
- If cptse is set, perform both segmentation and checksum offload
using the parameters in the TSO context; otherwise just do checksum
offload. (Currently the e1000 device incorrectly stores only one
context, which will be fixed in a subsequent patch.)
- Depending on the bits set in sum_needed, possibly perform L4
checksum offload and/or IP checksum offload, using the parameters in
the appropriate context.
Move these flags out of struct e1000x_txd_props, which is otherwise
dedicated to storing values from a context descriptor, and into the
per-packet TX struct.
