Re: [lwip-users] lwIP versus Interniche

[Timmy Brolin]

I think LwIP is much more memory efficient than Interniche. At least
when it comes to RAM.
Interniche requires that all rx buffers are of maximum frame size unless
you want to reallocate and copy each frame at the driver level. So even
small ACKs take a full ~1500Byte buffer.
