This is a trivial patch which adds capabilities for 8PSK (QPSK_8) and BPSK (QPSK_B) modes to frontend .h The change does not affect the size of the dvb_frontend_parameters, so it is backwards compatible with all software (for cards that don't utilize the 'modulation' value. I am not sure what to do about mixing software that does not support 8PSK modulation with hardware that does. In this case, there is the small chance that a program does not initialize the dvb_frontend_parameters, structure and that the value in the 'modulation' variable equals QPSK_8 or QPSK_B in which case any card looking for these will be switched to the wrong mode. Perhaps an additional 'union' is necessary to prevent that, however, these cards obey qpsk commands as well, and software I've looked at seems to assume a card uses only one of the available modes (qpsk/qam/vsb/ofdm) so it would mean a lot more coding to applications to treat 8PSK/BPSK as different from QPSK. Additionally, there is now only room for 8 additional capabilities in the fe_caps enum. I am open to other suggestions. This patch only includes the changes needed for frontend.h. As the last of three patches, I'll include one which uses these changes to support 8psk/bpsk on the genpix board, but I'd prefer to get feedback that the implementation I used here s the right strategy Signed off by: Alan Nisota <alannisota@xxxxxxxxx>
