With introduction of Raw modes, nRF70 driver now advertises get_c
onfig OP, but doesn't implement all types.
This causes problems two-fold with checksum calculations:
1. The "config" isn't uninitialized, so, every call returns differnet
values. So, for UDP header checksum would be done and
pkt->chksumdone would be set. But for IPv4 header checksum might be
skipped.
2. Even if we initialize to zero, then network stack gets all zeros
and calculates checksum by itself rendering offload moot.
There is another problem in #1, as there is only single flag for pkt for
all checksum, nRF70 driver sees this and tells UMAC to skip checksum for
the entire packet. The design isn't coherent, and should be converted to
communicate per-type checksum status (some are filled by network stack
and some HW).
But as nRF70 support all checksum offloads, advertise all types for both
RX and TX.
