The scatter Rx offload capability is needed for the pmd_buffer_scatter
test suite. The command that retrieves the capability is:
show port <port_id> rx_offload capabilities
The command also retrieves a lot of other capabilities (RX_OFFLOAD_*)
which are all added into a Flag. The Flag members correspond to NIC
capability names so a convenience function that looks for the supported
Flags in a testpmd output is also added.
The NIC capability names (mentioned above) are copy-pasted from the
Flag. Dynamic addition of Enum members runs into problems with typing
(mypy doesn't know about the members) and documentation generation
(Sphinx doesn't know about the members).

This was an interesting section, I'm not super familiar with bitwise
shifting in python flags so I figured I'd ask while it's in mind if
there's any specific reason for shifting these two flags? Not a critique
of the code, just genuinely curious.
It's there just to mirror the flags in DPDK code.
