Update from GP 1.0 the parity bits are now included in the DES and DES3
key sizes. This is an incompatible change where 56, 112 and 168 key sizes
are replaced with 64, 128 and 192 respectively.
This changes the ABI in a way that it's not enough even to recompile the
TA. In order to maintain backwards compatibility the configuration flag
CFG_COMPAT_GP10_DES is introduced (default y). The presence of the
parity bits is autodetected and this update is transparent to a TA which
hasn't been updated.
