title: TCP/IP Protocol stack without an OS
body: <p>I'm looking for a TCP/IP stack that can be used without an OS.  Our customer has an "aversion" to interrupts and doesn't want a real OS on a embedded board we're building.  It's desirable to move as much of the functionality to FPGA as possible due to the fact we will be only using a 50 to 100 MHz Arm.  And I'm pretty sure GPL licensed stuff won't be acceptable for this client. (Due to the legal quagmire associated with it.  They expect to have full unrestricted rights to the software once it's complete.)</p>
