P-Port Socket Buffer Size or Count Register
These registers contain the buffer size or count, depending on direction, of the corresponding socket (0..31). This is equal to
buffer_size/buffer_count in the corresponding DSCR_SIZE/DSCR_COUNT register. These registers are present in the
PMMC P-Port space only! No registers exist in the PP space, only the socket registers are read for this from the adapter. The
value of PP_BUF_SIZE_CNT is valid only if the PP_SOCK_STAT indicates ready for the corresponding socket.
