A higher number allows for more packets to be queued which may
|
||
|
|
improve throughput, but that requires more transient memory.
|
||
|
|
However there must be enough descriptors to hold all fragments
|
||
|
|
of a full-size packet to be transmitted or the packet will be
|
||
|
|
dropped.
|
||
|
|
|
||
|
|
Fragment size is influenced by CONFIG_NET_BUF_DATA_SIZE.

Received packets are spread across the required number of fragment
|
||
|
|
buffers. Each RX fragment has a size of CONFIG_NET_BUF_DATA_SIZE.
|
||
|
|
There is one descriptor entry per fragment.
