qtm-buf-mode {6ch | 4ch}
Set the NP7 QTM channel configuration for packet buffers.
6ch
6 DRAM channels for packet buffer.
This is the default setting.
4ch
4 DRAM channels for packet buffer. This is the safe mode setting.
In most cases, using 6 DRAM channels results in higher bandwidth. However, in some network configurations using 6 DRAM channels can cause packets to be dropped. Using 4 DRAM channels is a safer choice if the QTM engine gets into a stuck state and blocks packets.
