Data Fields
BufPool	msgbuf
	Pooled receive buffers, capped at queue creation.
PrQueue	msghdr
	Free NetMessage headers, so the steady-state packet path allocates nothing.

Detailed Description

Shared, capped pool of network message buffers and headers.

Queue-wide storage that anything holding a NetMessage keeps a reference to, so a buffer is always returned rather than destroyed. See Buffer Pool.

BufPool NetPool::msgbuf

Pooled receive buffers, capped at queue creation.

recvBufMax * recvBufSize is the entire receive-side memory ceiling. When the pool is dry the datagram path drops the packet and bumps droppedNoBuf rather than allocating; the stream path instead stops posting receives and lets TCP flow control apply backpressure.
