Why am I getting more split responses than before when running PPR with the new rev of E2920A software?

A recent revision of the E2920A software changed the default values of the split decoders such that each decoder always splits an incoming request.

PPR does not change these defaults. As a result more requests will be sent a split response than with the old version of software.

If you want to go back to the old defaults, execute the following API calls after the BestXOpen():

BestXCTSplitCondSet(handle, 0, BX_CTSPLIT_ADDRMASK_LO, 0xffffffff);

BX_CTSPLIT_CMDS_READBLOCK); BestXCTSplitCondSet(handle, 0,

BX_CTSPLIT_QUEUE, BX_CTSPLIT_QUEUE_A);
