modification history
--------------------
01g,28apr10,jmp  Updated WDB_SLIP_PKT_DEV to replace inBufBase[SLMTU] by a
                 buffer pointer.
		 Updated wdbSlipPktDevInit() prototype.
01f,27aug08,jpb  Renamed VSB header file
01e,24jun08,jpb  Added include path for kernel configurations options set in
                 vsb.  Renamed _WRS_VX_SMP to _WRS_CONFIG_SMP.
01d,05jul07,rlp  Made serial line packetizer driver SMP safe.
01c,26apr02,dat  Adding cplusplus protection, SPR 75017
01b,15jun95,ms	changed SIO_DEV to SIO_CHAN
01a,20dec94,ms  written.
