.SH "DESCRIPTION"
.PP
The function allocates Rx side skbs and puts the physical
address of these buffers into the RxD buffer pointers, so that the NIC
can DMA the received frame into these locations.
The NIC supports 3 receive modes, viz
1. single buffer,
2. three buffer and
3. Five buffer modes.
Each mode defines how many fragments the received frame will be split 
up into by the NIC. The frame is split into L3 header, L4 Header, 
L4 payload in three buffer mode and in 5 buffer mode, L4 payload itself
is split into 3 fragments. As of now only single buffer mode is
supported.
.SH "RETURN VALUE"
.PP
SUCCESS on success or an appropriate -ve value on failure.
