buffer descriptor chain to the VCC Table entry identified by the VCC_INDEX in
the first SBD. The VCC Table entry includes pointers to buffer descriptors for
segmentation. The SAR will link the new SBDs to the current chain of SBDs on a
VCC. The host can submit data to a VCC while the SAR is segmenting a
previously submitted message. Once the chain has been linked, the RS8234 resets
the transmit queue VLD bit to zero.

In either case, the SAR services one transmit queue entry by linking the new

Note that as the new buffers are submitted, the VCC is processing a single
buffer PDU (BOM/EOM). The RS8234 accepts new PDUs while it is
processing outstanding buffers.
