Some Kconfig symbols introduced in commit 8cb330355bd5 ("net: introduce
alternative implementation as net/lwip/") need a full description. The
NET symbol needs one, too.

Default value for TCP_WND in the lwIP configuration

Lower values result in slower wget transfer speeds in

general, especially when the latency on the network is high,

but QEMU with "-net user" needs no more than a few KB or the
|
|
transfer will stall and eventually time out.
